The center connection does appear to have more separation between the points and the solder around it... to an untrained eye anyways.
Ps; I also found some "solder dust?" in the cover below where this point is.
Fer sure - the middle picture is clearly a cold solder joint.
Remove all the old solder with a sucker or wick, and apply new electronics grade ROSIN core solder.
Do all 3 connections.
