Checking connection errors
Proxy, firewall, and network settings that are not configured correctly can cause connection errors.
If you are using the Edge Gateway standalone version, connection errors can occur if the firewall is not configured correctly. Make sure that the firewall is configured correctly as described by the procedure in Installing the standalone software.
Refer to the instructions in Configure proxy authentication. Because not all apps support proxy settings, refer to the app documentation to determine whether the proxy is supported for the app.
If the proxy and firewall are configured correctly but you still have connection issues, check with your networking team to make sure that the network is configured properly.
