Yeah, found problem it was my bad, actually GOG did try to update plugin, I was wrongly packed builds.
Fixed it now, GOG will autoupdate next versions seamlessly.

For those who have problems you need to remove wrong downloaded build here:
%LocalAppData%\GOG.com\Galaxy\plugins\downloaded\
Just remove anything inside this folder and restart GOG.

Hi toptaran,

I am getting this problem, where no matter how many times I try to sign in, it keeps giving this error... You plugin DID work initially, but now this :*(

Thanks in advance for your help!

Hi,
it can be some sony server problem, try manual NPSSO token way.

Thanks man! I did close the PSN login window with the 'X' in the corner after getting the same generic server error, and put in the NPSSO token after successfully logging into the official PSN login here:

https://www.playstation.com/en-us/playstation-network/

Then getting the NPSSO token here:

https://ca.account.sony.com/api/v1/ssocookie

Hope this helps anyone having the same problem that I did!

You're THE *BEST*, TOPTARAN!! :D

one question, have you seen the issue where the games are displayed as "Unknown game"? It's happening to me with some games, like Ghost of Yotei or FATAL FRAME: Mask of the Lunar Eclipse

Weird, I tested such thing before, if game does not present in gog database it shows name addon give and empty image.

ohh so, that's why I see some other games like that, the thing remastered for example, just the name and no image

but, in both cases, yotei and the thing, when I search in GOG, I'm able to see both games, I wonder if in the case of Yotei the fact that I bought the game the release day has something to do...

for the thing I have no idea

Try to find that game in addon logs, you can try to see it at gog database like this
https://gamesdb.gog.com/platforms/psn/external_releases/CUSA07412_00

Also you can try to find game here https://andshrew.github.io/PlayStation-Titles/
and find it 's title id in logs.

I see the id of Ghost of Yotei and The Thing in the logs, I attached 2 screenshots where you can see the ids, when I try to go to gamedb.gog replacing the CUSA value I get the not found message

These are the ids of the games

"concept":{"id":10003923,"titleIds":["PPSA26344_00","CUSA30701_00"],"name":"Ghost of Yōtei"
"concept":{"id":10011616,"titleIds":["CUSA49865_00","PPSA24381_00"],"name":"The Thing: Remastered"

and this is the gamedb url using the Ghost of Yotei info:

https://gamesdb.gog.com/platforms/psn/external_releases/CUSA30701_00

I'm not sure if this means the game info is not in the database.
