Hosting WCF Service within WinForm Application doesn't work when running the application executable

Over the past few weeks I have developed a 64-bit WinForms application that needs to communicate with a 32-bit DLL (job specs require it).
After doing some reading around the internet and finding out that there is not going to be any fun way of doing this, I decided to go with hosting a WCF Service Application within my WinForms application for communicating to the 32-bit DLL... or so I thought I was doing.
During development (while running within Visual Studio) it has been working really well, but of course, now that I need to deploy, I am running into problems. I am having trouble getting a strong enough understanding of WCF Services to know if I am going about this in a terrible way or if I am just missing some minute detail.
I created the project as Admin. After development was finished I tried to run the WinForm executable (both debug and release), WindowsFormsApplication1.exe. The application started up, but after I tried to complete a task involving the use of the WCF service, an exception was thrown:
This has led me to believe that Visual Studio was doing the hosting of the service during development instead of the WinForm application, or my configs and/or directory structures are incorrect.

Directory Where EXE resides:
The directory containing the WCF Service resides within the directory WcfService1 from the image above.
I have mostly been using the following method of instantiating the service:
ServiceReference1.Service1Client = new ServiceReference1.SErvice1Client();
Once I tried to switch to using a service host (below), but when I used that method, the service would timeout whenever it tried to communicate to the DLL.
Uri address = new Uri("http://localhost:44848/Service1.svc");
ServiceHost host = new ServiceHost(typeof(ServiceReference1.Service1Client), address);
host.Open();
And then I closed the host later. At this point, I am willing to try anything to get this working.
[EDIT] Below is the code of my WindowsFormsApplication1.exe.config file. All three contracts are giving the warning that they're "invalid according to its datatype 'clientContractType'". I think this could be the source of my problems, but I do not know why it is showing this warning:

Thank you for any help and guidance you can provide.

There is no endpoint configured for your service.

Above I have configured for Service2 ,similarly you have to configure for Service1 and Service3.

After sufficient struggling I decided to get rid of the WCF service that visual studio generates for you when you create it as a new project. I instead followed this tutorial verbatim:
Hosting Service In App
Doing this came with huge advantages:
No configuration file was necessary
Running it this way must've gotten rid of a large amount of overhead because the communication to the DLL (what I am using the service for) used to take several seconds to do large amounts of calls to the DLL, but now is able to handle 10k+ calls in the blink of an eye.
No service reference is necessary. I just needed the file for my main function, the file containing the service function implementations and the file containing the interface for the implementation.
So far, this has been the easiest and most robust way I have found for using a 32 bit DLL in a 64 bit application. Let me know if I can give any guidance for anyone else who may be struggling with this problem. I know this is not a fun thing to deal with if you've never done anything like it before.

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.

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"?>

Check 443 port is open and working.

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.

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.

Could anyone please help me, how can I correct this? I tried on net, however, not able to find any suitable tutorial for this. Please help.

This is resolved. Its was a proxy issue and after adding proxy to browser and IIS the issue got resolved. Thanks.

Does anyone have any idea?
Thanks,

Did you try this solution?
WCF by default limits messages to 65KB to avoid denial of service
attack with large messages. [...] To solve this issue you must
reconfigure your service to accept larger messages.
You need to set maxReceivedMessageSize in your binding. You can also
need to set readerQuotas.
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding maxReceivedMessageSize="10485760">
<readerQuotas ... />
