Bought a Great Stuff Pro 14 foam gun and a bottle of cleaner. Screw on cleaner and nothing. It looks like the threads are too deep to engage valve. I manually cleaned gun and everything is clean and working/moving, so it’s a mating problem. Even screwed on gun head and nothing. What the heck?

Great Stuff Pro Gun Won’t Clean

you're absolutely positive the gun is not plugged?
edit, I see you have the mounting flange off.
I think there's a ball bearing & spring in there to depress the can valve. is that intact?

The solvent cans for these are ****. I could never get one to seal, either--but mine sprayed solvent (acetone?) all over me and the shop when I screwed it on instead of just not working.
I just close the needle-valve fully when I park the gun and leave the foam can in it. Mine is now over five years old and still works fine. The foam won't harden unless it's exposed to air. I used it yesterday after it had sat for months and all I did was to scrape the hardened foam off the outside of the tip.

That's pretty much what I do as well but I have used the solvent cans without issue.The solvent cans for these are ****. I could never get one to seal, either--but mine sprayed solvent (acetone?) all over me and the shop when I screwed it on instead of just not working.

Positive. I can depress the ball bearing easily.you're absolutely positive the gun is not plugged?
