General Discussion / Re: Ubuntu 20.04 : Storage server connection error
« Last post by alain25 on March 23, 2024, 06:04:03 AM »Hello everyone,
I'm replying to myself, but it may help people.
If you see the error Storage server connection failed when you try to connect to Roundcube, it's probably because
- The Dovecot server is not working.
You can restart Dovecot with sudo systemctl restart dovecot and check its status with systemctl status dovecot.
- You are using a self-signed TLS certificate.
Roundcube requires a valid TLS certificate issued by a trusted certification authority, such as Let's Encrypt.
- Your TLS certificate has expired.
You can renew the Let's Encrypt TLS certificate with sudo certbot renew, then restart Postfix and Dovecot (sudo systemctl restart postfix dovecot).
You can also try adding a custom DNS entry to the /etc/hosts file, so that Roundcube can resolve the mail server hostname correctly.
Thanks a lot
