I tried using several softwares, like ngrok, localtunnel, forward, portforwarder,... But there seems to be nothing that works with Mezzmo. Al these softwares are working with things like Plex and emby and UMS or whatever, but no, not Mezzmo. I can open the Login Screen, but when I press login, it just loads and says connection timed out.

I know I can port forward to make Mezzmo work, but I have no access to my router so thats not an option.

Any help would be aprriciated a lot ;-)
