[Sync in China Update Requested]

Hi guys,

something I cannot understand in this context: I cannot get any connection between my PC in the office and NAS at home (in China). So far so "normal". But then the two connect without any problem to a client who sits in Germany! I really wonder how that works and wouldn't that be part of the solution?

Talking solution: can't Resilio set up alternative server/mirror in China? This should be relatively simple, or?

Thanks  for reporting, we'll try to reproduce in our lab and fix it.

If you want to delete old configuration - just open the .sync folder (it sits in the same folder where binary resides) and clean it up. Note, that you'll have to reconfigure your folders in this case. 

 

@maddhin

means that your Sync failed to subscribe to multicast addresses and won't be available for LAN discovery on the mentioned interface. There are other ways to discover peers (cache and tracker) so this message is not that critical, though if you have only one interface and tracker disabled - it might be a reason of peers not connecting.

 

These messages indicate that your router does not allow UPnP or NAT-PMP. It may prevent direct connections between peers if other peer also stays behind NAT. Though, in this case connection should simply go via relay server (again, if it is allowed).

 

Any observation on which peers are usually can't see others? local, internet? Also, are you using default folder properties or changed something?

 

hm, I extensively tested in the local LAN but "naturally" the results are the same vis internet. I, of course, switched on all options from using DHT, relay server, etc. waited for hours, etc. Even used predefined hosts as well as tried UPnP and manual portforwarding. No success.

 

What strikes me is that it works for certain folder pairs on different computers. Old versions of BTSync recognized the presence of the PCs/Laptop/Server and synced all folders related to this appliance. The "new" version seems to soley think in terms of folders and doesn't seem to share the found connections with other folders which also sync with this appliance/computer.

 

Not sure if this is a bug or by design but I still cannot get it to work the way it is supposed to work.

 

I could imagine this could also be a problem with the new authentification system. Maybe everything works fine in terms of network/connection but the key is wrong/expired/etc and it simply does not show a proper error message. (In case somebody asks: yes, I tried syncing a new folder but neither computer would show any peer = no sync).

 

Any help wouold be highly appreciated

I get

 

"failed to set IP_ADD_MEMBERSHIP for XXX.XXX.XXX.XXX:0: -1" errors on WIN7 (86 and 64) and

 

"UPnP: Device error "http://192.168.XXX.XXX:2869/upnphost/udhisapi.dll?content=uuid:XXX": (-2)

NAT-PMP: Unable to map port with NAT-PMP" von Linux (Qnap NAS) with this and 1.4.75 version.

 

It's very weird - I sync 4-5 folders between 2 laptops & NAS and 2 external PCs. Some folders sync between two machines instantly but e.g. the same folder won't sync at all on a third+ machine although in some wicked combination all computers are connected ("see eachother") but e.g. folder A on PC A is connect with PC B doesn't mean that folder B on PC A sees PC B and just shows "no peers" and never syncs. 

Something wrong.
