hi there!
i'm running a zabbix docker container, managed by plex. "everything worked fine" till someday i wasn't able to logon to the webfrontend, resulting in a "Unable to connect" from the browser.
i've checked telnet from my desktop pc on that port and it resulted in a connection refused
however, on the hosting vserver, using localhost, everything works fine
on the vserver using the external ip and not localhost i'm getting the same connection refused
so, looks like a iptables right?
i'm using the plesk firewall and i've setup a rule (Allow incoming from all on port 38080/tcp)
in iptables it looks like this
but that didn't fixed it.
i've also check fail2ban and disabled it for a second, but that didn't fixed it either.
anything i've missed here?
thanks
chester!

on the vserver using the external ip and not localhost i'm getting the same connection refused
so, looks like a iptables right?
i'm using the plesk firewall and i've setup a rule (Allow incoming from all on port 38080/tcp)
in iptables it looks like this
# iptables -L INPUT -v
Chain INPUT (policy DROP 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
[...]
231 12120 ACCEPT tcp -- any any anywhere anywhere tcp dpt:38080
but that didn't fixed it.
