Tips for increasing the likelihood of a response
- Use the
preformatted textformatting option in the editor for all log entries and configuration output. - If screenshots are useful, feel free to include them.
- If possible, also include key error output in text form so it can be searched for.
- Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
similar incidence here there was no resolution and the thread was closed. it’s really clogging up my log file with this error.
Additional info, my antivirus is clamav in docker with port exposed, other services are using the antivirus service without issues.
