AuthenticationException: The remote certificate is invalid because of errors in the certificate chain: NotTimeValid, UntrustedRoot

Question

I am struggling with following exception, which gets thrown in my Web API solution since today. I cannot find anything in my certicate storage.

I tried to clean my dev certs and reinstall as decribed in this post: AuthenticationException: The remote certificate is invalid because of errors in the certificate chain: UntrustedRoot

Extended exception details:

System.Security.Authentication.AuthenticationException: The remote certificate is invalid because of errors in the certificate chain: NotTimeValid, UntrustedRoot

at System.Net.Security.SslStream.SendAuthResetSignal(ProtocolToken message, ExceptionDispatchInfo exception)

at System.Net.Security.SslStream.CompleteHandshake(SslAuthenticationOptions sslAuthenticationOptions)

at System.Net.Security.SslStream.ForceAuthenticationAsync[TIOAdapter](TIOAdapter adapter, Boolean receiveFirst, Byte[] reAuthenticationData, Boolean isApm)

at System.Net.Http.ConnectHelper.EstablishSslConnectionAsync(SslClientAuthenticationOptions sslOptions, HttpRequestMessage request, Boolean async, Stream stream, CancellationToken cancellationToken)

Any ideas what to check else?

Deleted an expired certificate which was located in "%AppData%\Roaming\ASP.NET\https" folder

After running clean and trust for the dev certs everything worked well
