hi
at first, thanks for your answer.
maybe i didnt made it clear enough:
i open the site:
https://www.flyordie.com/backgammon/
in the center is the "start game" button and normally it pops up the new window (blue background)
with a dice and a loading bar and the order to wait 20 seconds till i can choose a room for backgammon.
this dice and loading bar disappear after a second and leaves me with the blue background.
it worked all well till yesterday. nothing changed on my side. no updates for browser or extentions etc.
hope this description helps better.
i am a foreign speaker, so please excuse my rather bad english :)
greetings
