Plesk Firewall Blocks Time Capsule

I host several sites on Media Temple using their Dedicated Virtual service running a Plesk Obsidian server.

After a recent rebuild, I upgraded the server and turned on the built in Firewall. At first it let me authenticate, but then had issues with the actual backups taking days and not making any progress, and some failed completely.

I removed the sites from the Time Capsule admin site, removed the plugins and moved the files to new folders on Google Drive.

When I tried to reconnect them, they failed completely. This seems a bit odd since I was able to at least connect just two days ago. After troubleshooting everything else and looking for anything online, I decided to turn off the firewall. As soon as I did, they could authenticate. Turned it back on, and authentication failed. At least one of them is backing up (the others are still “Sending all files to your Google Drive account… This may take a while” and calculating the size.

Of course, I’d love to turn the firewall back on again, and we’ll see if they are successful after this reinstall. Since the only thing that changed was the firewall setting, and the effect was immediate, I have to assume that was the problem.

Any help would be appreciated.
