When enabling or disabling a jail via the UI, the reload fails

[spacecitycoog]

I’m encountering a consistent reload failure in Docker (Unraid environment).

When enabling or disabling a jail via the UI, the reload fails and I get this error:
ERROR NOK: ('Failed to change log target',) Failed to change log target

However, running reload manually works perfectly:

docker exec -it fail2ban fail2ban-client reload

Returns: OK

Environment

• Unraid OS (Slackware-based)
• Docker
• Host networking
• Config mounted at /config
• File-based logtarget: /config/log/fail2ban/fail2ban.log

What I verified

• logtarget is defined only once in fail2ban.conf
• No overrides in jail.local or jail.d
• The log file exists and has correct permissions
• UI database does not store or override logtarget
• Runtime logtarget matches config fail2ban-client get logtarget
• Manual reload succeeds consistently
• Only UI-triggered jail operations fail

The failure only occurs when the reload is initiated via the UI during jail enable/disable.

Hi spacecitycoog, so i think your error is coming from the reload path used by your configuration.

Could you please:

• Confirm your connector type in UI (Local vs SSH) and configured socket path.
• Run reload from the Fail2ban-UI (server manager), are there any errors? check that the fail2ban socket is also mounted / reachable and visible in both containers. (if using local connector)
• Activate Debug mode & console in the settings and share debug log lines around the jail toggle request and full reload output.

cheers
