NEW Unexpected server response received. Please contact support.

When I try to upload a video I get an error "Unexpected server response received. Please contact support."

The problem has existed for several days, tried different videos it does not help.

I am getting the same error when trying to upload videos. Less than 300MB's. Of course, no VPN or proxy, all ad blockers disabled.
Tried with three different browsers.
