I keep getting an error message that says 400 Bad Request; Your browser sent an invalid request. It's only for one website so far and I tried clearing my cookies, but it didn't help. Has anyone else had this error message before?

It could also be an issue with how the website is handling users coming from a specific browser. In that case, please reach out to the respective organization to inform them about the issue.
