body: Hello Vinh,

Happy to help!

Users tend to run into that error when the application link was able to establish a connection with the remote application but no response was received. The possible causes for this can be:

* The remote application is in deadlock - For this, you can check that the remote application is operational, by accessing it as usual from the browser.
* There is a network connection problem - Use the tools to check the connection with the remote machine.

You can find very detailed information for network connections troubleshooting on the below page:

* [Network and Connectivity Troubleshooting Guide](https://confluence.atlassian.com/kb/network-and-connectivity-troubleshooting-guide-720405335.html#Networkandconnectivitytroubleshootingguide-tools)

I hope this helps! Let us know if you have any trouble.

Regards,

Shannon
