You're probably getting locked out by fail2ban, try to find a relevant log to for what reason fail2ban is blocking your ip

Re: cannot access mail.example.com and ssh

As 7t3chguy mentioned, fail2ban triggered iptables to block client IP address due to too many password failures or other errors. You should find this ip was banned and logged by Fail2ban in syslog log file (/var/log/message, or rsyslog).
