Failure with AuthorizationFailedException in

I am quite new to lets encrypt. For yours we create certificates for our Exchange Server (IIS)
Work perfect until start of Januray this year.

My domain is: exchange.grutzeck.loc

I ran this command:
[INFO] Let's Encrypt Windows Simple (LEWS)
[INFO] Software version 198.2.6594.21512 (RELEASE)
[INFO] IIS version 8.5

C:\letsencrypt-win-simple\letsencrypt.exe --renew --baseuri ""

It produced this output:
An exception was thrown while invoking the constructor 'Void .ctor(LetsEncrypt.ACME.Simple.Services.IInputService, LetsEncrypt.ACME.Simple.Services.IOptionsService, LetsEncrypt.ACME.Simple.Services.ILogService, LetsEncrypt.ACME.Simple.ISettingsService, LetsEncrypt.ACME.Simple.Services.ProxyService)' on type 'LetsEncryptClient'.---> Die Verbindung mit dem Remoteserver kann nicht hergestellt werden. (See inner exception for details.) (See inner exception for details.)

Tried to use the new WACS but it doesn't show the old certificate.
Creating a new one doesn't work.
What to do?

This (.loc) is not under a public TLD and thus cannot be certified by Let's Encrypt:
