### What happened?

Since updating to 1.82.3, some of the API keys that were created in liteLLM can no longer access any of the models.

Example with a valid key using curl (Same error appears when using the playground in the web UI)

``` yuri🐝bee:~> curl -s https://<liteLLM_url>/key/info -H "Authorization: Bearer <api_key>" | jq { "error": { "message": "Authentication Error, Invalid proxy server token passed. Received API Key = sk-...m31Q, Key Hash (Token) =<hash>. Unable to find token in cache or `LiteLLM_VerificationTokenTable`", "type": "token_not_found_in_db", "param": "key", "code": "401" } }

```

This key created a long time ago and has worked perfectly well. But since the update, the key can't make any sort of request, neither administrative (/key/info) nor model related (completions). The key is not disabled, or expired, or canceled.

We've been troubleshooting this for a few hours, and we can't determine why this happens.

I've found a few other issues that may be releated:
