Anyone knows about them?

Thanks

Other errors include

and

I don't expect those to be rocket science to fix, but, obviously if there's already a known solution or they're expected, why dig, right?

I think a lot of other errors I'm seeing, e.g.

are probably related to spammers/hackers so those are just a matter of tuning up fail2ban and my firewall rules.  Remember kids!  Good passwords and firewall hygiene!

I did a fresh install of Carbonio CE on a Linux Ubuntu 20.04 and the whole process went well and apparently everything is working. Analyzing the logs (syslog), something caught my attention and intrigued me:

service-discoverd: 2023-07-06T13:33:39.827-0300 agent.http: Request error: method=GET url=/v1/agent/self from=127.0.0.1:38104 error="Permission denied"

The other logs generated in this file are of the info and debug type, which I believe are normal, but this error is generated.

How to fix it? What impact does this bring to my environment if I ignore it?

Thanks,

André
