Uploads to Flickr frequently fail

Recently after buying a new computer (Mac Mini), I started getting this error message when attempting to publish to my Flickr account.  The message doesn't make any sense to me:

An internal error has occurred: Error Domain=NSXMLParserErrorDomain Code=4 "Line 1: Document is empty " UserInfo={NSLocalizedDescription=Line 1: Document is empty}

Does anyone know why I'm getting this and how to fix it?

Flickr is currently sick. Others reporting problems too:

Wait a day and see if it clears up. Follow the Flickr forum thread above.

Such errors used to happen a lot when Yahoo owned Flickr -- Yahoo was in its decade-long death spiral and drastically cut buck its competent technical staff. But since Smugmug bought Flickr, the problems have occurred much less often.

Usually Flickr eventually notices and fixes the issue.

Even after deleting the flickr authorization in Lightroom and reauthorizing it, the situation did not improve.

additional information.

Same error happens on mac OS: 14.1.2
