Api responses with 401

#1

Did you update API yesterday? It responses with 401 on requests with valid access token. But not always. Sometimes it responses with 200 OK, but mostly with 401. I did not change something in my code since yesterday, so I guess something went wrong after API update

#2

Seems It work as expected today

#3

There was no API changes, but a small issue with Redis cache that required a restart.
Sorry for the disruption.
