hello, I use latest version of aapanel and I try update to beta but same problem

CENTOS 8
latest version of panel but I try update to beta same problem
disabled fail2ban, firewall and selinux
-----------------------------------------------------------------------------------------------------------

if I reinstall os and panel (fix: remove manually dovecot, remove all folders and install, and panel repair):

Jan 21 19:13:11 myrotest dovecot[117377]: config: Warning: /etc/dovecot/conf.d/10-ssl.conf line 21: Global setting ssl_key won't change the setting inside an earlier filter at /etc/dovecot/conf.d/10-ssl.conf line 12 (if this is intentional, avoid this warning by moving the global setting before /etc/dovecot/conf.d/10-ssl.conf line 12)

error if I try connect with outlook (post client):

Jan 21 17:52:21 myrotest dovecot[86356]: imap-login: Disconnected: Too many invalid commands (no auth attempts in 0 secs): user=<>, rip=88.112.54.121, lip=194.182.80.85, session=<i5hDcRrWutVY1DZv>```

if I click to repair and restart services/server:

Jan 21 18:58:31 myrotest dovecot[93977]: master: Error: service(auth): command startup failed, throttling for 2.000 secs
