This error often appears during the installation/configuration/uninstallation of printers via the portal. Error says:
Cannot get terminal information for 10.10.10.10 from 126.96.36.199
Where 10.10.10.10 is a printer address and 188.8.131.52 is the server address.
The root cause is usually a blocked port 8700.
Execute the following command to verify connectivity, it should return a JSON response with the printer details.
$ curl -k https://184.108.40.206:8700/terminal?address=10.10.10.10
If there's an error, configure your firewall accordingly.
Other common mistake is using the Primary server instead of the gateway to deploy the embedded, so ensure that the Terminal Service in the Printer Setup is set to the local gateway.
Finally, check that the gateway is mapped to the IP/DNS correctly.
