Before we can proceed to further troubleshooting please try referring to this tutorial that provides information on the most common issues that might cause Internet-ID connectivity issues and provides solutions for them.
Please let us know if the solutions in the tutorial above did not help and the issue persists.
Could you please let me know which version of Remote Utilities do you use on both sides of the connection?
In addition, could you please provide us the log files for examination. It would be helpful if you could send us both Host and Viewer logs. Host logs are located in the following folder: C:\Program Files (x86)\Remote Utilities - Host\Logs\. In order to obtain the Viewer logs please follow this guide. You can send us the log files to email@example.com. Please do not publish the logs on the forum as they're considered to be personal information.
Could you please let me know what version of Remote Utilities do you use? In addition please let me know if all of the Hosts that are showing offline are located in the same network? If this is the case, then could you please try connecting to a remote Host in another network?
Last but not least, please try the following: 1. Fully exit the Viewer File -> Exit. 2. Locate the file config_4.xml in the C:\Users\[Your_username]\AppData\Roaming\Remote Utilities Files\ folder. Please note that the AppData folder might be hidden by default in which case you need to enable "Hidden files and folders" in Windows Explorer settings. 3. Remove the config_4.xml file from that folder (you can simply move it to another folder, just in case). This will reset the Viewer settings. Your address books won't be affected by this action. 4. Run the Viewer and register it with your license key once again. 5. See if you're able to connect to any of the remote Hosts or if they are showing online.
Could you please double-check and see if your remote Hosts are still showing offline and you cannot connect to them? We've found a minor issue on our servers that has affected the connectivity for older versions of Remote Utilities, so perhaps, your Hosts might have been affected as well. However, we've already fixed this issue. Could you please try connecting to your remote Hosts once again and see if it works? Sorry for the inconvenience.
