Syncthing won't start...qtls.ClientSessionState not compatible with tls.ClientSessionState


I run Syncthing on Centos7 and today syncthing crashed and i cannot boot it back up.

Looking at the system logs, this is what i see…

Aug 20 15:50:54 systemd[1]: Started Syncthing - Open Source Continuous File Synchronization for root. Aug 20 15:50:54 syncthing[11513]: panic: qtls.ClientSessionState not compatible with tls.ClientSessionState Aug 20 15:50:54 syncthing[11513]: goroutine 1 [running]: Aug 20 15:50:54 syncthing[11513]: Aug 20 15:50:54 syncthing[11513]: /builddir/build/BUILD/syncthing/pkg/mod/ +0x205 Aug 20 15:50:54 systemd[1]: syncthing@root.service: main process exited, code=exited, status=2/INVALIDARGUMENT Aug 20 15:50:54 systemd[1]: Unit syncthing@root.service entered failed state. Aug 20 15:50:54 systemd[1]: syncthing@root.service failed.

They built it wrong without testing, unfortunately. Use our binaries, or downgrade.

Thanks for the speedy response!

How can i downgrade? and will it affect the existing set-up?

I’m not sure, that’s a CentOS procedure. Downgrading might require resetting the database. Might be easier to just grab our binary for the same version from github. Hopefully once the package updates next time this will be sorted and you’ll be back on track.

Thanks a lot for you help!

Ran command to check my version which was 1.8, so got the binary for 1.8 from github but logs had “detected upgrade from 1.7 to 1.8” weirdly. Nevertheless all works fine!

The same problem appears on my raspberry pi. But this seems to work.
