We've encountered intermittent test failures that don't seem to be tied to a specific test case. The failures appear to be related to network issues in GitHub Actions, as rerunning the pipeline usually resolves them.

--- FAIL: TestUsersService_DeleteKey (0.00s)
    users_keys_test.go:170: Users.DeleteKey returned error: Delete "http://127.0.0.1:40547/api-v3/user/keys/1": net/http: HTTP/1.x transport connection broken: http: CloseIdleConnections called

Since we've observed this issue across multiple test cases, it might be worth investigating whether it's related to how the test server is being managed or if it's an underlying issue with GitHub Actions.
