I realize I forgot some information...
Im running Debian 11 on both servers and dovecot is installed using debian-packages, version 2.3.13 (89f716dc2)

I have computers at two different locations and one computer running dovecot at each place. I sync my emails between these two servers using ssh and I haven't had any problems with this lately until I upgraded dovecot recently.
I now get the following error at location "alfa" when trying to sync with dovecot at location "delta"
Jan 20 16:13:09 doveadm: Error: doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/10-ssl.conf line 16: ssl_cert: Can't open file /etc/letsencrypt/live/delta.oxyl.net/fullchain.pem: Permission denied

Trying to sync from "delta" i get the same error but the domain is changed in the error-message to 'alfa.oxyl.net'
I can read mail at both locations using STARTTLS. There is no error in dovecot.log when I restart the service. If I disable ssl and comment out ssl_cert/ssl_key in 10-ssl.conf I have no trouble performing sync between servers.
If I run the ssh-command in the error-message as user vmail I get the same ssl-error as above.
Any ideas how to solve this?
