Syncthing syncing on local network but not on other guest networks

I have a setup with Syncthing installed on ;

  • Synology DiskStation
  • 2 MacOS machines
  • 1 Windows Tablet running Windows 10

When all on the same (local) network synchronization works fine. If one of the two MacOS machines are connection to another (guest) network they still are able to synchronize. When Windows tablet is connected to the guest network the remote devices are disconnected and synchronization does not take place.

Although most company and guest networks will not allow inbound connections i enabled tcp:22000 for incoming connections.

When connected to the guest network and STTRACE set to discover and connections is see that it is able to join a relay Joined relay relay://71.120.2.222:22067.

Only noticable error is [F4E57] 2017/05/06 17:19:59.398953 global.go:142: DEBUG: globalClient.Lookup https://discovery-v4-4.syncthing.net/v2/?device=HOVGCY5-3ZZMHT4-KXJZMEA-3OCEXYD-YIZNQOF-P3P4J3U-IV2DGSH-DL2WUQG Get https://discovery-v4-4.syncthing.net/v2/?device=HOVGCY5-3ZZMHT4-KXJZMEA-3OCEXYD-YIZNQOF-P3P4J3U-IV2DGSH-DL2WUQG: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers) [

When entering the address in a browser (on a Mac) i also do get timeouts, so assume that this is not an issue related to the synchronization i have with the Windows Table.

Any help how to further resolve this issue ?

Here the full syncthing debug log when running on the Windows Tablet. It seems that it is able to access some discovery servers and able to join a relay at relay://178.19.96.186:22067. I can’t distill from the logfiles what goes wrong.

It’s trying to look up HOVGCY5 but the discovery servers don’t know anything about it. Either that device is offline or it’s not using global discovery. (Or it can’t, due to some firewall or other failure.)

I saw that too, but that is odd, because that is the Synology DS. The MacOS machines can synchronize with this node when on an guest network. Global discovery is enabled on this node (verified it). The NewYork machine may use UPnP and is able to make any outbound connection.

Hi Jakob,

I do not get it. Now connected one of the MacOS machines to the same guest network and synchronization with NewYork is working fine. The lookup of the discovery now returns an entry for HOVGCY5.

It looks like it’s not getting a response from the discovery server. Either it’s timing out or something is interfering with it? The usual Windows response to such issues are to disable any antivirus… I don’t know if that’s a thing on tablets.

Hi Jakob,

Was just fiddling with the firewal settings. Syncthing.exe has now access as an application and is allowed to make outbound connections. That did not help. There has been installed a s***load of security applications on that tablet, see if i can find what is interfering.

Seems i am getting a bit closer. When i open the url https://discovery-v4-4.syncthing.net/v2 in edge i do get a http 404. If i replace the hostname with the resolved ip-adres in the request https://95.85.19.244/v2 the certificate needs to be confirmed. So it seems that when using the ip-address i am able to connect. If i accept the certificate requests, i do get a bad request in the end from the server.

But what does prevent in windows 10 this ? Checked the firewall rules, no issues there. Since i am able to connect using the ip-address there must probably something filtering certain URIs …

You can surf to https://discovery-v4-4.syncthing.net/v2/?device=HOVGCY5-3ZZMHT4-KXJZMEA-3OCEXYD-YIZNQOF-P3P4J3U-IV2DGSH-DL2WUQG to see the discovery results for that device. If things work it should return a blob of JSON (or potentially 404 if the device is not registered). The discovery server optionally requests a client certificate so your browser may pop up a request for one - you can cancel that and it should proceed.

I have opened the urls to the discovery servers in edge browser, if doing so https://discovery-v4-3.synchting.net/v2/ the browser reports that the site is unavailable. If i resolve ip-addresses from the hostname and replace the host-name with the ip-address i am ablet to connect and import the certificate in the truststore.

Just to try i resolved discovery-v4-3.synchting.net to 95.85.19.244 and added https://95.85.19.244/v2/ as the only discovery in the configuration. When starting syncthing the log reports

 [F4E57] 2017/05/09 22:12:15.151947 global.go:142: DEBUG: globalClient.Lookup https://95.85.19.244/v2/?device=HOVGCY5-3ZZMHT4-KXJZMEA-3OCEXYD-YIZNQOF-P3P4J3U-IV2DGSH-DL2WUQG Get https://95.85.19.244/v2/?device=HOVGCY5-3ZZMHT4-KXJZMEA-3OCEXYD-YIZNQOF-P3P4J3U-IV2DGSH-DL2WUQG: x509: certificate signed by unknown authority

It seems that the certificates for the discovery servers are self signed. I can imagine that this is not allowed somewhere in the windows policies. Why are the certificates not signed? Nowaday cost cannot be an issue, https://letsencrypt.org, delivers signed certificates for free.

They are signed. You are not using a hostname, you are using an IP, and IPs do not have certificates.

While that is the reason for the failure, the discovery servers are actually authenticated by certificate pinning. When starting up, Syncthing prints something like this:

That ?id=... parameter (scroll that box to the right) tells Syncthing exactly what certificate to expect. Copy that into your configuration and you can use it by IP as well.

We do this because

  • it predates letsencrypt and similar
  • it works on devices that don’t have DNS (with the entries replaced by IPs)
  • it works on devices that don’t have an up to date root CA store.

Usage reporting, relays, and upgrades do use CA-signed certificates and thus requires a bit more functional infrastructure to work. For discovery we try to make sure it works even in the most broken environments, although some sort of unknown brokenness is winning in your case. :slight_smile:

That is not correct. DNS Name (not Hostnames) nor IP adresses do have certificates. Private keys of certificates are installed on a host which can be reached using the DNS name or IP-address. If the host is accessed using an ip-address or DNS Name not matching the name in the certificate a warning is shown that the certificate does not match the hostname.

The certificates are signed indeed, every certicate is signed, these are self-signed which is not the same as signed by a Root CA.

Did you read my post above?

Hi Jakob,

Yes just did read it, already tried to open these URI’s but then IE / Edge will not open the URIs and give the error “This page can’t be displayed. Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings”.

And as you might guess, these are all enabled.

Hello everyone, I think I’m actually having the same issue. At home my Android device can connect my Work place Linux PC when my Home PC can’t. I also have this log message: "dial failed QQK52EX tcp://113.118.227.179:22000 dial tcp 113.118.227.179:22000: i/o timeout" I uninstalled my COMODO firewall, and it seems that windows firewall configuration is ok. I don’t understand What I have to do to solve it.

Hi,

I do not think this is the same issue. The i/o timeout is something different. The ip-address 113.118.227.179 is probably a non routable address or a firewall on either side blocks the port. Can you connect using telnet 113.118.227.179 22000 ? If you get a blank screen after executing the telnet command you are able to connect, if not the port on the specified ip-address is not reachable.

Cheers, Peter

Hi Jakob,

Thanks for the responses, but still no-go. After spending quite some hours debugging, testing, trying, screaming :wink: i give up. If you have more ideas, i am willing to try them out, but for now will leave it.

Cheers, Peter
