Code 319045 - No party Chat & Communities Error 2024

Dear Gents,

Kindly be informed that in the same maintinance day which has been done on 6/12/2024 my in-game party chat stopped working and all communities are not showing leave/rejoin button anymore. It is just disappeard. When i try to chat in communities i directly get a message says " This community is not avaliable at this time. Please try again later. (Code 319045).

I Have submitted a ticket to support but their replay is leading me to open a topic here, Updated all my drives and tried to repair game files from battlenet. I even tried to run the game as Administrator but there is no improvement is showing. It was working fine for months but during the maintinance activity this problem started.

Appreciate your kind support.

Regards,
