TimeoutException: The operation has timed out.

[kirill-kostenetskyi]

All works great on my Windows machine, but every time when I tried to do login or registration from an app hosted on Linux machine I got TimeoutException: The operation has timed out.
This looks like this issue https://github.com/dotnet/corefx/issues/4631#issuecomment-165893079

@neustart That's weird. What's the linux and postgres version that you are using? Sorry for the delay in answer it

The problem occurs only when you try to login or register? Did you had a chance to test in another cenario like loading something from a table?
