Hi everybody,
After Debian 11 updates installation, login to server not possible any more. In WEB GUI user get: Logon failed. Please verify your credentials and try again.
Outlook during start repeatedly ask for user credentials. If you want to connect Outlook into server it tells: not possible create secure connection to the server, click NEXT to try with unsecure connection?
At logfile nginx-web-error.log I found: 2022/12/08 15:52:40 [error] 798#798: *4409 FastCGI sent in stderr: "PHP message: grommunio Web user: user@domain.eu: authentication failure at MAPI" while reading response header from upstream, client: 10.0.0.251, server: _, request: "POST /web/?logon HTTP/2.0", upstream: "fastcgi://unix:/run/php-fpm/grommunio-web:", host: "10.1.1.199"
In Admin GUI all services seems to work OK 🙁
Can someone shortly tell where should I dig, please? It is a bit critical for me. Thank you very much for each advice.
