400 Bad Request

[Eco]

For the last 2 days I have had "400 Bad Request" messages practically everywhere. On the phone, in Steam Guard part of the app, on the computer while going into Steam Community discussions. Of course, not all the time, because, as you can see, I have written about it. Am I the only one having that problem? Is there any way to fix it, while it shows on the computer and on the phone?

This error could be a server-sided problem, and it's just reported as 400 bad request.

However, you could consider flushing your DNS cache and also changing your DNS settings.

Last night was the regular scheduled maintenance, so if you had problems, it could be that.
