Cannot access WCF service using hostname IIS

I've been facing a tough issue for three days. I have a WCF web api (.svc service file) deployed to an IIS 8.5. The application was working properly and then, suddenly, after I changed some other minor things inside the code, this problem arises: I can connect to the application from inside the server (using localhost). I can connect from outside, using the server IP address. But I cannot, by any means, connect from the outside by using server hostname. The problem is best understood through the examples bellow:
Note: the application is an IIS app inside the main Web Site. The service's URI is http://myhostname/api/servicos.svc
http://localhost/api/servico/some_request: works!
http://server_ip_address/api/servico/some_request: works!
http://myhostname.com/api/servico/some_request: DOES NOT WORK!
I have searched through many websites and forums but of no avail.
My web.config:

The error I am presented to when trying to access the API from outside (via hostname) is this:
Server Error in '/Api' Application.
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its
dependencies) could have been removed, had its name changed, or is
temporarily unavailable. Please review the following URL and make
sure that it is spelled correctly.
Requested URL: /Api/servico.svc/asos/csv/09655055000104
Version Information: Microsoft .NET Framework Version:4.0.30319;
ASP.NET Version:4.6.1069.1
Do you have any idea what should I do in order to fix this bug?
Edit: one more information: other apps inside the same web site in IIS works FINE! There are even other web apis written in C#, just like this one here, and they all work properly.
Edit 2: another thing important to say is that I can access the service path until the service itself (servico.svc). So, for example, when I try to access "http://myhostname.com/api/servico.svc?wsdl" I successfully get the service's metadata. So, only when I try to access the service itself I get the error mentioned above.

There is a file named host file. When you try request a DN windows look into that file. That file inside C:\WINDOWS\System32\drivers\etc there is host file. Append like below this in your host file (with admin mode).
server_ip_address myhostname.com

I finally got it solved! For those struggling with this issue without sucess: Amazon EC2 load balance was the cause of my troubles.
It happened that Load Balance was set up to filter all requests and send them to the server machines using transport layer SSL security protocol (HTTPS). So, if I were to request http://myserver.com/servico Amazon Load Balance would internally redirect to https://machine-n/servico where 'n' is the machine used (in my case, I have two machines).
So, what caused my issue, inside WCF, was this: my web.config was not allowing the service to accept HTTPS requests. Once I fixed this, everything worked fine.
It also explains why everything worked when I requested directly using the machine's IP address using HTTP: load balance did not play any role in this case filtering the request and redireting using HTTPS.
So, here we have my web.config, now allowing HTTPS requests:
<?xml version="1.0" encoding="UTF-8"?>
...
<system.serviceModel>
<services>
<service name="ServicoWeb.servico" behaviorConfiguration="Wcf_Behavior">
<endpoint name="" binding="webHttpBinding" contract="IServico" bindingConfiguration="webHttpTransportSecurity" />
</service>
</services>
<bindings>
<webHttpBinding>
<binding name="webHttpTransportSecurity">
<security mode="Transport" />

</behaviors>
<protocolMapping>
<add binding="basicHttpsBinding" scheme="https" />
</protocolMapping>
<serviceHostingEnvironment aspNetCompatibilityEnabled="false" multipleSiteBindingsEnabled="true" />
</system.serviceModel>
...

In my case below things helped :
Check protocolMapping is binded correctly.
<protocolMapping>
<add binding="basicHttpsBinding" scheme="https" />
</protocolMapping>
Check 443 port is open and working.

Unable to consume WCF service in mvc5 application when trying to get through add service reference

Hi I am developing small application using WCF,MVC4 and angularJS. I am refering following URL
https://code.msdn.microsoft.com/AngularJS-Shopping-Cart-8d4dde90#content
When i tried to add service reference in my mvc application I am getting below error
Metadata publishing for this service is currently disabled.
I gave below url to access service.
http://localhost:55835/Service1.svc
When i tried I am getting error. I am unable to add service reference in my application. I am little worried about my web.config file. This is my web.config file.
<system.web>
<compilation debug="true" targetFramework="4.5.2" />
<httpRuntime targetFramework="4.5.2" />
<httpModules>
<add name="ApplicationInsightsWebTracking" type="Microsoft.ApplicationInsights.Web.ApplicationInsightsHttpModule, Microsoft.AI.Web" />
</httpModules>
</system.web>
<system.serviceModel>
<behaviors>
<endpointBehaviors>
<behavior>
<webHttp helpEnabled="True"/>
</behavior>
</endpointBehaviors>
</behaviors>
<protocolMapping>
<add binding="webHttpBinding" scheme="http" />
</protocolMapping>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
</system.serviceModel>
Can someone tell me something I am missing anything in config file?
Thank you in advance.

This problem is displaying because you are not enabling metadata.Metadata(wsdl document for your service code) is neccessary because your client will generate proxy class on the basis of your metadata(wsdl code). If you will not enable your metadata then your client will never know how to implement the same kind of code in its's proxy classes.And this can be enabled under servicemetadata tag under servicebehavior tag by setting httpGetEnabled to true.
Add this line of code under servicebehavior tag just after </endpointBehaviors> tag.(please do not include <behaviour> tag again)
<behaviors>
<serviceBehaviors>
<behavior>
<!-- To avoid disclosing metadata information, set the values below to false before deployment -->
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" httpGetUrl="true"/>
</behavior>

WCF Workflow Service - How to add Workflow Control Endpoint?

I've created a new WCF Workflow Service project in VS2012.
Ultimately, what I need is the ability to terminate instance B of my workflow from instance A of my workflow.
As best I can tell, the only way to achieve that is via the Workflow Control Endpoint, but I can't figure out how to add/access that to my project.
From what I've seen (e.g. here), to add the control endpoint, you just add an <endpoint> element to <service> node in web.config with the appropriate attribute values. The problem is.. I don't have a <service> element in my web.config. The "WCF Workflow Service Application" project template does not add one. My web.config is below.
So my question is simply: Starting from the "WCF Workflow Service Application" project template, how do I add a Workflow Control Endpoint?
These are the default launch settings for the project:
web.config
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
</appSettings>
<system.web>
<compilation debug="true" strict="false" explicit="true" targetFramework="4.5" >
</compilation>
<httpRuntime targetFramework="4.5"/>
</system.web>
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
<protocolMapping>
<add binding="basicHttpsBinding" scheme="https" />
</protocolMapping>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>
</configuration>

Finally found a solution for this. See this post.

There was no endpoint listening at {0} that could accept the message. This is often cause by an incorrect address or SOAP action. (Xamarin Android)

I can normally run the application on the emulator and do some action before, but for some reason this suddenly appeared even though the webservice runs properly on the browser.
I looked for a solution with similar case as this but I can't seem to figure out how to do it because I am using Xamarin which has a different way of adding service reference.
Here are my codes:
ServiceReferences.ClientConfig
<?xml version="1.0" encoding="utf-8"?>

</connectionStrings>
<appSettings>

</appSettings>
<system.web>
<compilation debug="true" targetFramework="4.5"/>
<httpRuntime targetFramework="4.5"/>
<httpModules>
<add name="ApplicationInsightsWebTracking" type="Microsoft.ApplicationInsights.Web.ApplicationInsightsHttpModule, Microsoft.AI.Web"/>
</httpModules>
</system.web>
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior>
<!-- To avoid disclosing metadata information, set the values below to false before deployment -->
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
<!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
<protocolMapping>
<add binding="basicHttpsBinding" scheme="https"/>
</protocolMapping>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true">
<remove name="ApplicationInsightsWebTracking"/>
<add name="ApplicationInsightsWebTracking" type="Microsoft.ApplicationInsights.Web.ApplicationInsightsHttpModule, Microsoft.AI.Web"
preCondition="managedHandler"/>
</modules>
<!--

Set to false before deployment to avoid disclosing web app folder information.
-->
<directoryBrowse enabled="true"/>
<validation validateIntegratedModeConfiguration="false"/>
</system.webServer>
</configuration>

Which emulator are you using it might be the problem of your emulator. Use genymotion emulator it is the works smooth without any problems. And a service hosted on localhost can be accessed through a proxy or with the IP.

Already solved by creating a webservice again and now it is working properly.
