ASP.NET Core ErrorCode = '0x80004005 : e0434352

I tried to publish identityserver project to azure app service & also IIS service on VM. But neither works. I checked the error code on app service. Development/production environment works on development machine.

Application 'MACHINE/WEBROOT/APPHOST/PROJECT' with physical root 'D:\home\site\wwwroot\' failed to start process with commandline 'dotnet .\PROJECT.dll', ErrorCode = '0x80004005 : e0434352.

Error for both ways seems identical

turns out due to persistentdbcontext is not accessible at program.cs in production on IIS/Azure.
