I Install Virtualmin en EC2 Ubuntu server. The installation finish, but I cant access to de virtualmin admin al port 10000, and I lost connection to my EC2 server via Putty.
Have you tried rebooting via the AWS controls, I’ve had no luck using EC2 free versions, always locked up. Actually lockup during install, my install never finished.
No it won’t the firewall block IP’s as instructed via fail2ban. However the provider firewall may not have the port open that ssh is running on. In this case there is to little info to draw a conclusion
