I have been facing a very weird issue with a simple web application that I have recently deployed using IIS. This is an already working application in a server in NA region. I re-created the same exact IIS environment in a new server from a different region. When I try to login using the new URL, I get the following error message.
I have double-checked multiple times that my IIS configuration is exactly same as my old (working) server.
Here is what I have selected for the Authentication setting of the server.
Kindly help with the pointers. Thank you.

Seeing 502 error for the past 6 hours.
Tried restarting the server but it didn't do anything.
It is hosted on a VM (instead of being an Azure Web App).
Azure region: North Europe.
App Insights resource didn't report of any problem.
Website is written in mvc core.
What do I do to fix this?
If you have already tried the link suggested by DonNetMatt, then, here is what I would do.
You said you are hosting it in a VM. could you try redeploying the site to another server (web app or VM), and if possible another region. This should tell you if the issue is really with your web app or the server.
In all likelihood, the redeploy should load the site just fine, in which case contacting Azure support is the best way to solve this issue.
I doubt if the issue is on your code. With the error you are getting, its likely a server issue on Microsoft Azure side.
(Note : I am assuming when you say 'Website is writting in mvc core' you mean, website is written in mvc core. Or, is your website designed to write code as part of some automation thing, and generating MVC code?)
I am building a Office 365 application using ASP.net Visual studio 2015 Enterprise. When I run the application in visual studio using IIS Express it run fine everything works. I am able to authenticate with Azure AD and be routed back to my start page. However, when I deploy it to the IIS SERVER, I am able to authenticate but after authenticating I am routed back to a WHITE screen.

I DO NOT WANT TO HOST IN THE CLOUD!!
I tried using Fiddler but that didn't help me that much. Have anyone ever ran into this problem or similar? Were you able to get around it without hosting in the cloud?
I had this same problem - it worked fine in IIS Express, but in IIS I would get a 400-Bad Request (header too large) error and the page would just spin. To fix this:
Make sure your app login and your reply URL are the same in Azure. Make sure the PostLogoutRedirectUri in your app matches as well.
That URL in step 1 should not be a page! This is what got me I think. I had https://localhost/testdirectory/default.aspx when I should have only had https://localhost/testdirectory/. Once all 3 places matched, things started working in IIS as well.
You probably know this but make sure you're using HTTPS, not HTTP.
I am having an issue getting an HttpClient to work from a Windows Azure website. When running the site from my local machine or a local server it is able to connect to the web services without issue. However, once I publish it to Azure it returns a 404 error from the SendAsync method. I would assume a network problem except that if I do a $.getJSON(...) call to the exact same service from the exact same site I get the response back with no issue. I have tried everything I could think of but am currently out of ideas, has anyone experienced anything like this?
I used the following guide to set up IdentityServer for deploying to Azure: http://weblogs.thinktecture.com/cweyer/2013/01/running-thinktecture-identityserver-v2-in-a-windows-azure-web-role-from-zero-to-hero-a-walkthrough.html
I got all the way until actually running the Azure site locally, but when I attempt to start it, I receive a 500.19 error in IIS Express.
I have googled this error endlessly, but every solution has failed. Oddly, if I start IISExpress for the WebSite from the Command Prompt, I'm able to visit the site without issue. I'm certain this is an issue with the Azure Emulator, but I'm not sure how or why...
Thanks!
I am trying to upload a file to blob in asp.net azure. I am getting success if the page is without ssl. but if i upload with https page then i am getting connection was reset error.
And also I mentioned the maxrequestlength in web.config.
This is not Azure specific error instead it is an ASP.NET specific problem. I did some test if I could hit the problem but no luck..
I am getting sure that the problem is introduced by adding maxrequestlength and potentially having request filtering. You must setup the timeout setting with length and support script runtime in webserver specific settings.
You also have one option to RDP to your instance and enable IIS debugging to understand what could be the problem:

After running Debug Diagnostic Tool v1.2, please share your log, and i will look for root cause.
