My syncthing is no longer functioning, the GUI works just fine and I can create new folder syncs, but… syncthing is refusing to discover devices on my local network.
It worked fine for a good while, now it will not work. I’ve whitelisted all the STUN subdomains that is listed in the documentation through my adguard home. Still doesn’t work.
Please try disabling AdGuard completely and see what happens then. Also, please post screenshots of your Syncthing Web GUI, specifically the “Discovery” and “Listeners” information under “This Device”. Click on each of them and share screenshots of what you see there.
