# NousResearch/hermes-agent · Fix auxiliary client 401 auth refresh bug

## Open now

- Nothing open on GitHub.

These items address a bug where the auxiliary client fails to recover after receiving a 401 error, because a fresh client is cached under a different key than the one used for lookup. The fix ensures expired credentials are evicted and refreshed under the correct cache key.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `unresolved`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.
- Pairwise link density `0.67`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.
