I have a rpi connected to a LAN and it’s running syncthing. The system works, but it’s kind of slow and looking at the logs I’m receiving this error:
INFO: UPnP parse: unrecognized UPnP device of type
INFO: Dialer for kcp://[IP]:12086: unknown address scheme “kcp”
The LAN goes like this:
MODEM - Dumb Bridge ROUTER - Eero router = rpi, my machine, etc.
I’ve read the documentation but it’s not clear to me what kind of magic should I do on the rpi to avoid this weird error I don’t understand.
Thanks a lot in advance
Both are just informational and don’t signify anything really bad, hence the
INFO. The first is that your router says something odd over UPnP, the other is that another device is able to speak KCP which apparently your Syncthing doesn’t understand. You should probably upgrade Syncthing.
But all my Syncthings are updated to the last version. So, what you are saying is my speed issues are not connected with this part of the log, right? It’s weird anyway.
Possibly, if the UPnP issue prevents a port forward from being established and the connection falls back to using relaying.
If you are on the latest version you must be on an odd build, “kcp” should not be an “unknown address scheme” since several versions back.

0.14.18 is a year old, no wonder it doesn’t know kcp. You should definitely upgrade that device.
