Question Blocked IP, where is stored?

[A.Mason]

I have problem with server based on Debian and Plesk. Somehow i have blocked my IP.
In IPTables i have only two lines with my IP (whitelist):
0 0 ACCEPT udp -- * * .......MyIP........ 0.0.0.0/0
0 0 ACCEPT tcp -- * * .......MyIP........ 0.0.0.0/0

I have add my IP into whitelist of:
- Fail2Ban
- DDoS Deflate Interface
and i have ad my IP to allow all connection in firewall rules.

I have turned off Fail2Ban, DDoS and firewall, and restart server - still the same.

I there any other place where my IP could be blocked?
