I also had the UDP port blocked issue, on a recent iMac running latest OS (Catalina OS 10.15.4) and Fios. I tried all the tweaks: designating a range of ports, make sure JamKazam is permitted by the firewall, turn off firewall off completely, reboot computer, reboot router, etc. Nothing worked.
Finally, I just deleted JamKazam from my Mac and reinstalled it. I believe I made the settings exactly as before, but it just worked. I've jammed 3 times now since then.
Maybe something had gotten corrupted that the reinstall replaced, or maybe I simply changed a setting that I'm unaware of, but my suggestion is to delete and reinstall the app, lame as that might sound. At worst, this will be like the suggestion to reboot computer or router.
Good luck.
