As said before we have 2 1.4 TB shops on the same vps with ubuntu 20.04 and Apache and php 7.4. Server 2 has no issues.
Firewall settings allow 80, 443 ssh. SSH is only allowed from 1 IP. Nothing more. I have blocked port 25 in and out because we had spamattacks on that server
For the computer I run Linux Mint, no FW no antivirus
And cnfig has not changed for at least one year on the server, more than package updates. No new modules and now updated modules
Now when updating to 1.5 is not working, would it be possible to migrate to a new server with a fresh TB install?
