We just ran into an in issue in our project where we were getting a 401 error when trying to contact our custom domain we are using for the api. It has been working no problem and then stopped.
now it is working again and we didn't change anything?
Thoughts?
TL;DR
Intermittent 401 error on custom domain for API, issue randomly appeared and disappeared without changes. Possible server-side authentication problem causing intermittent access issues. Check server logs for more information.
