Could be the brand I attempted to use at the time. I finally tried another can, but much newer, then no problem.

“unless the surface is thoroughly sanded (or use steel wool or a wire brush)”
Maybe because of oxidation or formation of some microscopic coating on the copper, it has to be sanded or abraded before solder will attach. Also could be that the sanding creates an abraded / non-smooth surface that makes it easier for the solder to attach to the copper. Just sand it.
