@pcexantiuno What kind of OpenVPN server do you have? Can you test OpenVPN connect 3.6.0 client on your PC, does it work? Not all OpenVPN Servers are supported with Omada, but more have been...

@GTR_Sanj yes, it's only the ES switches that don't show the IP address.

@ANAWA start by upgrading your router, it is so old and outdated and many problems have been fixed, the latest official version is 1.3.0 you can find it here...

@RBL What happens if you try to install 1.0.1 then? You can install it even if it's the same one you have to test if you get the same error.

@RBL It's not exactly the same, my switch got 1.0.2 so not exactly the same firmware, maybe there's a bug in the version you're trying.

@RBL Strange, I have almost same switch (ES205GP) and it upgraded without any problems, but as the message says, the switch must have access to the management port, do you have something blocking it?
