Websocket connections to critical Microsoft 365 domains

Please check the status of websocket connection using Microsoft 365 Copilot network connectivity test if you suspect any issue with it, if the web tool returns success then there is no action needed from your side, based on your writeup I am guessing there are no websocket issues. Regarding the network insight notification for websocket connectivity errors, we are updating the mechanism for websocket connection tests reporting and if you have already raised this issue with support, I am almost certain that this should go away for your tenant in the coming weeks.
