The current software OS for all models seem to have expired certificates and so I encountered an issue with my VPN provider rejecting my attempts to connect to their OpenVPN server because the client-side certificates on the GL-iNet routers are expired.
I’ve contacted GL-iNet technical support and explained how to resolve this and requested they update the packages in their latest update as well as their available software app/plug-in library, but they haven’t done so (it’s been months.)
So I’m going to post the fix here in case anyone else has this issue:
These are the two packages you need to install from the Advanced Admin interface on the router.
I have tested these with the 3.xxx operating system on both B1300 and AR-750 units and on both devices it resolves the expired OpenSSL certificate issue.
In the Advanced Admin Panel - in the packages page - load the following two packages and then restart the device.
