I have copied the working cookie from MS Edge but it have the same problem

It seems that without a cookie, the captcha error message now always comes up, even if there are no captchas to solve in the Edge browser. With a new cookie token, however, the request still seems to work without an error message. I hope there will be a solution for this captcha problem. It was nice to be able to use the chat without having to copy any strings from the browser :)

I have the same issue, is there a work-around to this?

I noticed that when you are not logged in there is no _U cookie. Maybe something has changed in the way of communication with a guest account.

I use the BingChat library in my KATI application. In the app, a redirect link is displayed when you have to solve a captcha. When you click on it, you are basically redirected to the Edge browser, where you can solve the captcha. You have to be logged in to the Edge Browser with the same account from which you copied the U_ token. After restarting the KATI application, the captcha message is normally no longer displayed. But as I said, with a guest account it doesn't seem to work anymore. I also hope that this can be fixed :)

Here is the link to the KATI App, if someone wants to play around with it^^

Worked for me: Log in to your browser. Use the cookie-value and ask one simple question or simply type HI to bing. Then the verification is done and the cookie-value works.
So if this error occurs just ensure you have the same cookie-value and say hi to bing - this does the verification.

Hiere is a Tutorial using the nuget package and solving this problem: https://youtu.be/17w5wSBiXkI (sry. German Language)

I am facing the same issue. Can we solve this without using Cookie Value and saying Hi to Bing?
