Hi there, I am struggling to get syncthing to sync, not sure what I have set up wrongly, here is an SSTRACE. I would appreciate any suggestions! 🙂

It looks fine, it managed to connect, can you define not syncing? Also screenshots from both sides would help.

Thanks Audrius, here are the screenshots.

As you can see from the first image, of the RPI-web-gui I cant even get much info from the, and the sstrace gives me:

> 2015/08/11 16:06:15 http: TLS handshake error from 192.168.0.3:57520: read tcp 192.168.0.3:57520: i/o timeout

The desktop’s sycthing seems to work fine, it sent a 50mg test file to the laptop, then when I deleted it on the laptop, it was deleted on the desktop. But, none of this works for the rpi. The rpi also seems to be hung at “Syncing 50%” for example.

Thanks for your help 🙂

Yeah I don’t have the GUI open normally (following your precious advice Alex) and I also have adjusted the pingtimeouts on all the computers - its just I was asked for a screenshot and thats all I can get from the RPI. It still doesn’t sync even when the gui is closed - thats the issue here for me

I think its still going through the initial scan/index exchange as it’s failing to even load the ui properly (unless you really don’t have any folders)

Yeah, I think you are right… It must have been still doing the initial index/scan. I’m just impatient!

It seems to be working now, 6+ hours after starting up Syncthing on the RPI. Btsync didn’t take anywhere near as long, with the index or the sync, so that gave me the wrong measure for how long it should be taking.

Thanks for your help and patience @AudriusButkevicius and @Alex

Also, @Alex is syncthing-bolt much better for the RPI? Would it be better for people to use that?

I don’t need to increase pingTimeout with that any more, running it for almost 3 weeks now without problems. But you need to rescan everything again when switching 😉
