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".

 

 

Cannot connect while screen locked (Android)

 

If SyncBackPro cannot connect to SyncBack Touch on an Android device, while the Android device is locked, and SyncBackPro is connecting using the name, then you may need to connect using the IP address (see above).

 

 

Port 8080 and 8081

 

By default SyncBack Touch listens for connections on port 8080 and also uses port 8081 if Rapid Transfer is being used. However, port 8080 may also be used by some web servers (typically for testing or development). Because of this you may need to change the base 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   (which means port 8082 will be used for Rapid Transfer)

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.

 

If you are using Rapid Transfer, then an extra TCP port is required. It will also use the port above the port you defined. For example, if you are using port 8080 then port 8081 will be used for Rapid Transfer.

 

 

Firewalls and Routers

 

By default SyncBack Touch uses TCP port 8080 for all communication with SyncBack and also port 8081 if Rapid Transfer is being used. The base 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 (and the next one above if using Rapid Transfer). 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.

 

 

Running?

 

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.

 

 

Accessing SD Card

 

To access the SD card (in an Android device) you may need to set your destination path to use the variable %SBT_EXTSDCARD%
