fly destroy <app> fails with API error

Questions / Help
1

command:
fly destroy -y app-name --verbose

response:
Error You ran into an error connecting to the Fly API. If the error persists, keep this request ID to help Fly Support track it down: 01G5EVA5JVERK1P62R4GA79GZJ-fra

Same error when I try to delete the app via the web interface:

You ran into an error connecting to the Fly API. If the error persists, keep this request ID to help Fly Support track it down: 01G5EVRFCQ0M9NZ8ATSFZWD34H-fra

Context:
I deleted the postgresql database cluster (two regions) first, expecting the apps running in two regions to fail. Failures to connect (as expected) were visible in the app logs. After that destroying the app fails.

Same issue:

I was deleting the deployed application, with a volume of 1GB and several secrets set up. I’ve done it several times before, but now I got this problem.

Issue resolved. Tried again today and successfully destroyed the app.
