Getting server error 503 from server after multiple refreshes

I have setup a subdomain via wildcard in my asp.net application. The subdomain routing works perfect, but for some reason if I refresh the page two times quickly I keep getting this error:
The remote server returned an error: (503) Server Unavailable.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

The subdomain route is setup like this:
routes.MapSubDomainRoute("OtherRoute",
"{someValue}", // SubDomain
"{action}/{id}", // URL with parameters
new { controller = "Other", action = "Index", id = UrlParameter.Optional }, // Parameter defaults
new { someValue = new SubDomainConstraint() } // constraint so we only deal the subdomains we want
);
what could be the reason behind this issue ? Can someone help me out?
And the subdomain that I'm trying to access is:
http://subdomain.example.com/routeIdParameter

api cannot reach the installed servera

Asp.Net Mvc Web App PowerBI Login HRESULT E_FAIL Error

I am trying to have a single sign-in web app through azure that has an initial Microsoft login and then no second login. At the moment I am just trying to get 2 logins to work but when running locally I can get the app to work and show the Power BI reports using a dual login. But whenever I publish the app up to the Azure host and I try to access the power BI page instead of having a Microsoft popup to log in it just suffers from this error.

Any help would be greatly appreciated as I have no idea why it works offline but not online and I don't know how to understand the stack trace
This is the Authentication code
private void Authenticate()

string clientID = ""; // We have our client ID here that was created in power BI dev apps
string redirectUri = "https://localhost:44367/";

}
}

HRESULT E_FAIL has been returned from a call to a COM component.
have no idea why it works offline but not online and I don't know how to understand the stack trace
According to the exception, it seems that you application try to access to out-of-process COM in the WebApp, but it is restricted in the Web App sandbox.
If it is restricted in the WebApp and Cloudservice is possible, please have try to use Cloudservice. About how to Migrate and Publish a Web Application to an Azure Cloud Service from Visual Studio, we could refer to this document.

I am getting this error at the moment and I am pretty sure it has to do with the fact that my azure app does not have the "Access the directory as the signed-in user" permission, since I am accessing Power BI as a master user as in the" App owns data" scenario.
Notes:
I only get this error when I unwind the aggregate exception. Otherwise the error message is "One or more errors occurred." Here is a good link on that: Flattening of Aggregate Exceptions
It looks like I have the permission, and that I have the rights to grant it, but when I click on the Grant permissions icon I get an error message saying I cannot grant that permission myself.
In fact the Azure documentation is clear here that you can grant that permission yourself only for Application Type:Native App, not Web app/API which is what I have here (so the UI has a display bug). Here is a link to it:Permission Scope Docs
I am still trying to figure out who my "Admin" is so that I can get this permission, so I am not yet sure that this is the whole issue. Will update.

System.Globalization.CultureInfo.GetCultures returning null in dev environment (Visual Studio)

First of all, this could very well be a rookie mistake on my part, I'm fairly new to .net and c#.
I'm using the CMS system Umbraco on our latest project, and a recent update has meant the system has started using the System.Globalization.CultureInfo class to deal with localization. This has resulted in multiple "Culture Not Found" errors in the CMS back office that renders it unusable. Here's a stack trace from one of them:

I'm still not completely sure where the .-no is coming from, but after some amount of research into this I tried running the following code with a breakpoint inserted:
var locale = CultureInfo.GetCultures(CultureTypes.AllCultures & ~CultureTypes.NeutralCultures);
This returned null, and doesn't seem to be throwing an exception anywhere. I'm guessing this might be the cause of the errors, judging by the stack trace. Could this be an issue with my local setup? I'm running Windows 10, mainly in a virtualization environment, but it can also run natively via OSX Bootcamp, where the problem still seems to be present. I've also tried using Powershell to output the list of installed cultures, and that works fine.
If it helps, I'm using IISExpress for the web server and the database is running under SQL Server 2016 Express.
Thanks in advance! Let me know if I can supply any extra info to help out with this.

Make use of the fact that Umbraco is open source.
Judging from the stack trace and exception details you have provided, problem is caused by this line:
https://github.com/umbraco/Umbraco-CMS/blob/dev-v7/src/Umbraco.Core/Services/LocalizedTextServiceFileSources.cs#L102
Apparently invalid value .-no is passed into GetCultureInfo method. If you look a bit up in the source code, it seems that this value comes from XML file name or XML file content.
I cannot provide complete solution for your problem, but here are some things to try to pinpoint root cause of it:
1) Clean deployment folder
Do full clean & rebuild cycle
2) Check localization XML files to check if they contain valid cultures
If you have edited files manually, make sure there is no typo there.
3) Compare folders of "fresh" install and your non-working solution folder
Check if update hasn't left behind some XML files from previous versions;

Cant find image in network drive

I know this question have been asking many times but none of then have solved my situation.
I have this simple code
Image f = Image.FromFile(#"\\NetWork\imagenes\folder0\1690D-PC.tif");
But it throws:
System.IO.FileNotFoundException \\NetWork\imagenes\folder0\1690D-PC.tif
I have total access to the related network
I do can find the image in that location. I copy the path, START + r, pasted the path and the image opens.
Is the same for all images in that server.
But the situation not only remains there:
I tested in another pc to checked if is was a IIS problem or
whatever, but when I tested it throws the same(2 pc cannot access to
that file, having they full access... weird...)
When im in development, I can find the image everything work normaly, but when i deploy and
upload to my local iis and the other pc, throw the related exception(FileNotFoundException).
My parner has the same code(almost the same proyect, just with some
diferrent functionality and public) and he can find the image and
display it.
I ran into this situation last friday and i havent came up with a solution yet.
Im willing to hear all your suggestions.
Update 2.
More info:
There are 2 more application that request images from that server and those application can find it normally. Those application are in my local IIS.
Updte

Please help to be aware. Thanks.

VerifyProvider will throw if you are using the SimpleMembershipProvider and it is not yet initialized, or if the provider does not inherit from ExtendedMembershipProvider.
If you are using WebSecurity out of the box, you need to make sure WebSecurity.InitializeDatabaseConnection is called first.
If you are using custom providers, make sure they are inheriting from ExtendedMembershipProvider (or SimpleMembershipProvider), otherwise you cannot use this function.
