cant login with out of games plugin

Greetings !so far, the out games plugin synced the collection in the deck tracker worked great. But I tried to set it up at home a week ago, and when I go to the login page, I log in to the outofgames page, but nothing changes in the deck tracker. In the game, it says to log in so that it can synchronize.Now I log out even here, where it worked, and I can't do it again here either, it doesn't work.Válaszát előre is köszönöm !
