It looks like you're trying to make use of Bing's new AI chat mode.
There's not a lot to go on, and diagnosing the issue would require more information than you've provided. 🤔
You've tried a lot of things, but none of them relate to the root cause.
- Are you using a profile with Edge?
- If you are using a new account, have you verified the account credentials yet?
- Are you accessing Bing from a workplace that may have IT policies that block AI communication?
- Are you using any browser extensions that might interfere with Bing AI?
I suggest you try connecting to Bing AI on your mobile data, or from another internet connection, log into your profile in the browser and signing into Bing.com - this could determine if your internet connection or the 4 computers have configurations preventing communication with Bing AI.
