Default. Didn't know you could change it.

Sounds like we're probably having the same issue, then. I haven't changed mine either. It requires you to ssh in and open up the config file to change what relay Alby Hub uses.
Beware that if/when you do this, all your current NWC strings will break and you will need to set them all up again.
The Alby relay works 99.99% of the time so I don't worry with it but I do have my own relay and a test node running AlbyHub also. 🤔
it’s likely a bug in the latest hub release which happens in some edge case and it looses the connection (independent of the relay used)
a patch release is prepared and will be ready tomorrow.
Thanks nostr:npub1xv8mzscll8vvy5rsdw7dcqtd2j268a6yupr6gzqh86f2ulhy9kkqmclk3x! I figured it was on Alby Hub's side of things, because the transactions I had attempted were going through once I restarted the Hub, so it was seeing the payment requests sitting on the relay as soon as it reconnected.
