Relates to: #17831 (comment) ### Motivation When the `ProxyConnection` handles a `Connect` command, that is the time to go to `Connecting` state. There is no other time that makes sense to switch to connecting. The current logic will go to connecting in certain re-authentication scenarios, but those are incorrect. By moving the state change to earlier in the logic, we make the state transition clearer and prevent corrupted state. ### Modifications * Remove `state = State.Connecting` from the `doAuthentication` method, which is called multiple times for various reasons * Add `state = State.Connecting` to the start of the `handleConnect` method. ### Verifying this change The existing tests will verify this change, and reading through the code makes it clear this is a correct change. ### Does this pull request potentially affect one of the following parts: Not a breaking change. ### Documentation - [x] `doc-not-needed` It would be nice to map out the state transitions for our connection classes. That is our of the scope of this small improvement. ### Matching PR in forked repository PR in forked repository: michaeljmarshall#21
