Able to add Minecraft server via Playit-provided IP but not the public address

Installed and setup on my server PC running Debian > CasaOS > Crafty Controller using these guides:

So I can add and connect to the server in Minecraft if I use the IP that Playit gives (in green) but not with the public address. Anything I can do to fix this?

Your public IP doesn’t have to do anything with it. Playit.gg gives an IP address, and that is the only one, that you can use to connect (I prefer the second one, 100.78.10.54:19922 [It is just an example])
