Chat blocked - Profanity Filter never initializes

My in-game chat has not been working since yesterday.

This is not limited to Trade Chat. Local Chat, Party/Group Chat, and Trade Chat are all completely blocked. I cannot send or receive messages in any channel.

Every time I try to use chat, I receive this message:

“Chat access will be blocked until profanity filter is initialized.”

The game shows that I successfully joined the chat channels, but the profanity filter never initializes and all chat remains blocked.

I have restarted Diablo IV and Battle.net multiple times, but the issue still persists.

This issue started yesterday and is still happening today (September 26, 2026).

Platform: PC
Season: Season 15

Please investigate this issue. Thank you.
