Description
This issue has been migrated from [#6699](https://github.com/matrix-org/synapse/issues/6699).
---
`/federation/v1/user/keys/claim` seems to randomly time out, which may be a cause of UISIs. Also possibly related to https://github.com/vector-im/riot-web/issues/11836
e.g. I see some occurrences of things such as
```
POST-203- {POST-O-258} [matrix.org] Request failed: POST matrix://matrix.org/_matrix/federation/v1/user/keys/claim: ResponseNeverReceived:[CancelledError()]
