Description

My log level is set to trace, failed attempts (Permission denied (publickey)) do not appear in gitea.log (I also enabled and checked access.log)
This seems to be a regression of #5765 introduced in #7250
Authenticated connections are still logged but the IP address is not (which was also logged before this regression)
