SonoffLAN: Cloud error: cannot found access token info

All of my entities suddenly stopped working today after a long time of not touching anything. I can log in to ewelink normally, tried re-adding the integration.

From debug page:

cannot found access token info - is this tied to dev token maybe? Then everyone would have the same issue?
