I have two macOS laptops running Syncthing-macos 1.7.0-1. They talk to each other just fine.
One talks to and synchronizes with a third machine - the richb-Vostro-3550 machine running Ubuntu 18.04. The other macOS laptop does not, but gives an error message, No compatible QUIC version found. We support [QUIC WG draft-28], server offered [0xff000016 0xyadaea4a]
(see screen shot below).
Any thoughts on diagnosing why the one computer works, and the second does not? I attach the log messages below the screen shot. What other diagnostic information could I provide? Many thanks.
The logs show:
