I have now managed to get a new access token, but I'm still unable to get data using OAuth2, using the current release 2022-02-02. I get a 403 error each time.
This is not the issue of upgrade SERP. But serverip.dat in this case contains the value: 192.168.88.12:1301, so this is local IP of the server with SERP.
Anyway I don't understand what do you me...
