Comment 1 Fabio Valentini 2020-08-23 12:18:25 UTC 
Ugh. I thought I had worked around this issue by building syncthing with "noquic":
https://src.fedoraproject.org/rpms/syncthing/blob/11ede8be92e4a96f54525fa325da51282b60708d/f/syncthing.spec#_284
But it looks like that doesn't work.

The next syncthing release (1.9.0) should have the proper fix for the quic+go1.15 issue ... sorry about the trouble.
