As explained in the topic. What I see in my connection list is "offline / repeat". I can click on "repeat" and I get questioned for "steam username" and "steam password", afterwards I'll get a continue button. Once I press that steam sends me a verification code to the email I defined at steam. After that....... nothing!

What happens? Is it broken?

Thanks for the information - as is said in the first link: the integrations are usermade and independent from gog.
Both links are outdated and last checked January 2024. First link refers to version 1.2.1. Second link refers to version 1.0.8.

My conclusion: this link is done for. Not updated, not working.
No complains. Did not know it was outside of gog! No way to upgrade somebody's FREE contribution.

Thanks. No solution, but question is answered.

That's what community means. It's no secret (see screenshot).

Sorry. My mistake. I did not see it. Sometimes someone is just to dense to see what is written. This is on me!

I'd say you can try opening a new issue ticket, but the maintainer of the integration hasn't had any activity past December 2023. I'm afraid it's likely the project has been abandoned.

Maybe try a reply in the first thread I linked to above. The OP there is pretty knowledgeable; it's worth a shot.
