How to reinitialize camera upload after server replacement?

Had Plex server installed on server box 1 and camera upload worked just fine from the Android app.
Have now installed Plex server on server box 2, discarded box 1.
App version 6.4.1.1644 (660d012c), Server version 1.8.1.4139 @ QNAP NAS.

New server has different internal IP but same public IP, same public port as old one.

Did not think of disabling camera upload first. New server is working wonderfully, but camera upload fails. “check your connection and try again.” When I go the camera upload settings in the Android app, hoping to disable then re-enable upload, I get a “Camera upload error: the selected server isn’t reachable. Check your connection and try again” message. I hit OK and am back in the settings root menu.

How on earth can I re-initialize the upload feature?

Interesting to see that nobody at Plex cared :frowning:
Good to know that I could resolve this issue by uninstalling, then reinstalling the Plex Android app.

bump. same problem

same problem here. Not sure what to do here…

So, I completely uninstalled/reinstalled the app. Now I was able to setup the camera upload again. Unfortunately, it is now syncing everything again, including everything that had already been synced…
