SyncBack Touch Connection Problems

Previous pageReturn to chapter overviewNext page


For SyncBackPro to connect to SyncBack Touch, it needs to connect to the computer that SyncBack Touch is installed on. This means it is very important that the connection details are correct.



Automatically Finding SyncBack Touch


If SyncBack Touch is on the same local network as SyncBackPro, e.g. the computer your are using SyncBackPro on and the computer SyncBack Touch is running on are both at home or both in the same office, then SyncBackPro should be able to automatically find SyncBack Touch on your network. To do this simply click the Find button when creating your profile or modifying it. If SyncBackPro cannot find your SyncBack Touch installation then it could be that your firewall is blocking UDP port 24671. Also, it could be that SyncBack Touch is on a different subnet.


If SyncBackPro is not on the same local network then you will need to enter the connection details manually (see below).



Manually Entering SyncBack Touch Connection Details


If SyncBack Touch is not on the same local network as SyncBackPro, e.g. it's on a computer you need to access via the Internet, or you SyncBackPro cannot automatically find your SyncBack Touch installation (e.g. it's on a different subnet), then you'll need to enter the connection details manually.


For SyncBackPro to connect to SyncBack Touch it needs two things:


1.The I.P. address, or hostname, of the remote computer SyncBack Touch is running on.

2.The TCP port number the remote SyncBack Touch is listening on. By default, it is port 8080.


Make sure to untick the checkbox "Find and connect to the SyncBack Touch device using its name".



Port 8080


By default SyncBack Touch listens for connections on port 8080. However, this port number may also be used by some web servers (typically for testing or development). Because of this you may need to change the port number SyncBack Touch listens on. If your are using SyncBack Touch on Android or macOS then you can change the port number via the user interface on SyncBack Touch itself.


With Linux, you need to use the command line to set the listening port:


Using the command prompt, go to the directory that SyncBack Touch is installed in, e.g. cd /home/username

Run the SyncBack Touch executable and pass the new port number using -port portnumber, e.g. SyncBackTouch -port 8081

Restart SyncBack Touch


Alternatively, you can specify the port number during installation of SyncBack Touch.


If you can connect to SyncBack Touch using SyncBackPro then you can using SyncBackPro itself to change the port. To do this, modify a profile that connects to SyncBack Touch, go to the SyncBack Touch settings page and click the Configure button.



Firewalls and Routers


By default SyncBack Touch uses TCP port 8080 for all communication with SyncBack. This port number can be changed/set during the installation (see below) or by using SyncBack. If you want to access SyncBack Touch through a firewall then you must open this port. If SyncBack Touch is behind a router then you may need to enable port forwarding. Refer to your routers documentation for details.


To discover SyncBack Touch installations broadcasts are made on the UDP port 24671. You may need to open this port on your firewall (not your router as broadcasts are only made on the local network).



Virtual Private Network (VPN)


If you are using a VPN (either on the device running SyncBackTouch and/or on the device running SyncBackPro) then it's very likely that either broadcasting will not work and/or the connection will not work.





Check to make sure SyncBack Touch is actually running on the device you are connecting to. If it's on Android, then simply start SyncBack Touch. If it's in Windows then check the Windows services to see if the SyncBack Touch service is running.
