Can't connect Sparrow Wallet with Umbrel

Electrs is permanently stuck on 99% when synchronising, so I’m not sure if this is the problem. I’ve tried these steps, but it hasn’t resolved the issue: https://www.reddit.com/r/getumbrel/comments/ylpzqs/must_try_commands_to_fix_everything_wrong_with/?utm_source=share&utm_medium=web2x&context=3

When I try to set up a private electrum server using my Electrs onion url and hit 'Test Connection" Sparrow returns

Could not connect:

Cannot connect to hidden service

Connection failed: IO Error (Cannot connect to hidden service)

Any thoughts?

Can you also SSH and try this command @bc1?

~/umbrel/scripts/app restart electrs

Let me know if this gets you to 100% sync’d and connected
