Ok so please don't judge I absolutely know this was so stupid . We have been having many hack attempts on our server and I was sick of it. So before going on holiday I decided to edit the firewall in plesk so all attempts to access the server could only come from our ip addresses and I wouldn't be bothered during the holiday with hack attempts and websites being hacked etc. And that worked great. But now I am back and after the holiday I got really sick. So I haven't accessed the server for over a month. And now its obvious the license had to be updated in the meantime, but the server itself (ip address) had no access to do this because it is not in the list. And therefore I can't do anything anymore. I can access the server via console, but I have no idea how to add the iptables rule in SSH for updating plesk with the ip address of our server. Does anyone know the command line for me with just the word "IP" where I should type our IP address? Again, YES I know it was very stupid indeed, I have learned my lesson.
