Kinda sounds like you were using the Party Finder system to look for running a low level dungeon. Few players, if any, will utilize that system. You might get a few bites if you explain that you just want to do something low level easy to learn the ropes. But, if it doesn't really matter who or how you get a group, just queue up for the content. The Duty Finder will get a group of players together and dump you in.

Also yeah. If Party Finder was that sparse, likely also you're on during the off hours.
