Firewall Bug with CSF

I encountered a strange behaviour after enabling CSF.
Every time I restart server I am unable to ssh to it. Not from inside the panel not directly. If I go to “ConfigServer Services” and restart CSF there nothing changes,
but when I go to Security >> CSF … it take 10-20sec. to load the page and then I can ssh to server aiagin :neutral: ???
seems like a bug with ports provisioning.
Also I noticed that " Secuity >> Firewall " page is blank now.
