Looks like a service unavailable but since the issue was raised before (#47120) I'm raising it for consistency.

Mark mentioned a similar build failure:

https://gradle-enterprise.elastic.co/s/42cmniylhr7g4/tests/lgycqkw2bfw46-clvf2uhrzpiw4

I suspect an issue on the server side logic, so I added some logging in #48991 in case it reproduces.

This just happened again on an intake build:

@tlrx just had this fail on me here https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+pull-request-1/10613/testReport/junit/org.elasticsearch.repositories.azure/AzureBlobStoreRepositoryTests/testIndicesDeletedFromRepository/ and it had the new logging active :)
