Access Token stopped working - Connection App problem - INVALID_SESSION_ID

I'm facing a problem with one of my Sandboxes. Today I noticed that Access Token received from Connected App doesn't work (Session expired or invalid - INVALID_SESSION_ID). It's weird because everything was working fine on Friday. I created another app, but it still has the same problem. I also created Connected App on my private Developer Org and I still can't retrieve any data. I'm suspecting, that it can be general Salesforce problem, do you have the same problem with your connected apps?

Thanks in advance.

Hi Łukasz,

Greetings to you!

Your app needs permissions (scope) to have the ability to use refresh tokens.
In Setup > Quick Find > App Manager >, click the "Edit" link for your Connected App and add the scope "Perform requests on your behalf at any time (refresh_token, offline_access)".

Once this has saved (you may have to wait a while), you will be able to change the value for the refresh token policy.
