Bustacap: workaround until they fix it:
- log in to PSN (store.playstation.com) through your browser
- after the login open this link:
https://ca.account.sony.com/api/v1/ssocookie Copy content of "npsso"
- open windows explorer and enter the following into the address bar at the top and press enter
%LocalAppData%\GOG.com\Galaxy\plugins\installed\
- open the psn_{random number} folder and edit the plugin.py file with your favourite text editor
- go to line 64 and change it from:
stored_npsso = stored_credentials.get("npsso") if stored_credentials else None
to:
stored_npsso = "Copied value of npsso"
("copied value of npsso" should be a 64 character long text consisting of numbers, lower case letters and upper case letters)
(the quotation marks " " are important!)
- restart GOG Galaxy
- try connecting with PSN again
You, my good sir, are an absolute hero!
I came across this problem earlier today, figured I'd google it ('cause internet knows best) and over the past day I see you have helped tons of people with this already, and now I'm lucky to be one of them as well!
To anyone trying this and running into problems, as mentioned by several people before, make sure you delete everything on the line after the copied npsso string (i.e. delete the "if stored_credentials else None" part).
Also, make sure you log in to the playstation store site, not the playstation network site: I tried that first, and then the link provided by Bustacap doesn't work. Honestly though, that's entirely on me for not actually following the instructions and assuming those two sites would be the same... ;)
