Syncing stuck / extremely slow

Worked fine yesterday, now suddenly I want to sync my steam deck with my home pc it is stuck at 73% and sometimes it unstucks but downloads at 1-2 bytes/second. I haven’t changed anything at all since then so this is strange..

Logs if that helps : 2025-11-30 19:06:31 INF syncthing v2.0.11 "Hafnium Hornet" (go1.25.3 windows-amd - Pastebin.com

I have the same problem although I’m not sure if it’s for the same reason, but I have a feeling it may be. Same behaviour (uploads/downloads often stuck at 0B/s). I’m using Fedora 43 and my Firewall allows syncthing. Haven’t found a solution yet.
