I managed to fix my problem (syncing with Dropbox): - I couldn't connect to the App Store previously, so that option was out. I decided to address that issue by upgrading to Mac OS Mojave. - Once the OS was upgraded, I removed the standalone app (it still didn't connect) and deleted everything except for the backups via the Enpass app - I then downloaded the app via the App Store - I authenticated via Dropbox, got the redirect prompt and this time Enpass synced with my Dropbox account! @iota – Depending on your situation, you may want to try something similar. Hope you get your problem sorted!

I came here to say I am experiencing the same thing, only with Dropbox :( I previously set up syncing then yesterday saw that it was no longer connected to Dropbox. When I tried reconnecting I received an error code of 204007. I deleted my local instance (except for the backups) and now get Something went wrong. Error -1.
