Re: login problem

Did you check iptables rules when this issue happening? For example, check current iptables rules in memory, not just in config file:

# iptables -L -n

Maybe you can find your client's IP address.

Re: login problem

I guess this client had several times of password failure, then Fail2ban invokes iptables to ban it. That's what Fail2ban does.
You can update /etc/fail2ban/jail.local to force Fail2ban to ignore your client IP addresses.
