Since version 5.4, we have been getting random 401 errors when trying to access the API using either user/password or an API key.
When this happens, since our scripts keep trying to connect to our Testrail instance, the account gets locked out and then we have to wait some time before attempting the connection again.
The strange part is, this seems to be random. At one moment it is working, at the next it starts responding with 401 errors, then the account gets locked, then it usually works again and the cycle repeats.
On the admin backend, we have confirmed that the API is enabled to be used.
Is there any reason why this could have started happening after the update to v220.127.116.1159?
