Why wouldn't 60/40 Rosin Core Solder work outside? That's news to me and I

have used it forever on any electrical connection inside or outside without

any problems. What did I miss?

For one, you missed corrosion. Things tend to be dirty outside. Dirt acts as carrier of humidity (read; electrolyte). Copper - Tin/Lead is dissimilar metals and that in combination with the electrolyte results in speedy corrotion of the solder joint.
