The firewall seems to be intermittently blocking a single user from registering and 100% from using the FOP. I can however ping the machine from the users IP with no issues…
I have whitelisted the IP and it still does not work. If I disable the firewall it works fine. No other users are experiencing this issue.
There is no reference of the IP in question via iptables
There is no reference of the IP in any fail2ban jails
The IP is not listed in the ‘blocked hosts’ section
There is no reference to the IP in the ‘banned’ section in the GUI.
There are no IP’s listed on the ‘blacklist’
As soon as I disable the firewall it works fine.
