Azure Asp.NET Core 1.1 process crashed and Restarting in a loop

I have deployed .NET core 1.1 App in Azure web apps but it never starts completely, I keep on getting 500 timeouts. Also in eventLog i get this error Application 'MACHINE/WEBROOT/APPHOST/SOAPBOX' with physical root 'D:\home\site\wwwroot\' created process with commandline 'dotnet .\M.dll' but either crashed or did not reponse or did not listen on the given port '12588', ErrorCode = '0x800705b4'

It keeps on restarting again and again, Strange thing is sometimes it just works after a couple of above messages in event logs I get another message saying it has successfully started listening on '123123' port. I have enabled stdout logs but it keeps on generating empty files with no content.
