Code 499, type 100, Invalid Authorization Header


All of a sudden we have started receving this error when using a BizTalk service. We haven’t had this problem before. Anyone know what this means?

Doesn’t look like an error code Cloudflare shows. This is an error coming directly from the origin server (I guess BizTalk). Check your error logs (audit logs?) and make sure the auth method your client uses is correct.
