Encountering 'Error 678: The remote computer did not respond'


I’m facing an issue with my Sierra Wireless modem. When I try to establish a connection, I keep receiving an ‘Error 678: The remote computer did not respond’ message. I’ve checked all the settings, and everything looks to be configured correctly. I’m using the latest firmware version, and the signal strength is strong.

Could anyone please help to resolve the issue ? I appreciate any suggestions you can provide.

Thank you in advance!

Thank you
