Fail2Ban blocking Server IP

My server’s internal IP is

For some reason, something is using that address instead of the loopback address. After Every Server reboot, Certain things break.
I get this when i check IPtables

Chain fail2ban-SIP (3 references)
target prot opt source destination
DROP all – anywhere

When i check intrusion Detection under system settings, i have 1 or 2 entries under banned ip’s as

If i click restart , those disapear along with the offending rules in iptables and everything starts working as normal.

I’ve even tried and allow entry fir but i assume deny entries take precedence.

Any ideas as to what could be causing this?
