Child sites with WPTC installed do not stay connected to Main WP (Time Capsule)

I am evaluating the WPTC plugin for backups with a trial account and installed it on two sites that are connected to my MainWP dashboard – except after I hit the sync sites button, those two sites get disconnected. Adding Time Capsule is the only variable that has changed with the sites.

I added Time Capsule to each site, signed in, and got it synced to S3 storage before syncing with MainWP. I tried signing out of my WPTC account on one of the child sites, and re-adding it to the dashboard, but the next time I hit “sync sites” it disconnected again. When I hit reconnect, I get a “Public key already set. Please deactivate & reactivate the MainWP Child plugin on the child site and try again.” notice.

I would love to use this feature as I have been having trouble finding a way to run reliable offsite backups via MainWP, which is a crucial feature for my needs. My clients are often on different hosting set ups, one of the offending sites is on GoDaddy, the other is on SiteGround. I have made sure to Whitelist the IP addresses for the necessary services.

Here is my mainwp details:

Hey Traci,

Welcome to the MainWP community!

I’ve installed Time Capsule on multiple sites and enabled the Time Capsule extension on the MainWP Dashboard.

Synchronizing does not disconnect them, nor does any other action I’ve performed via the Dashboard.

Can you try deactivating the Time Capsule extension on the Dashboard and Time Capsule on one of the child sites?
Then, try reconnecting the disconnected site by deactivating and then reactivating the MainWP Child plugin and using the Reconnect function in the Dashboard.
Finally, try syncing the site again and see if it disconnects.
