Ewon Flexy 201 Error VPN

Hello everyone,
It’s been 1 month or so since this ewon was working correctly, and I see that today it was disconnected. When I remotely connect to the physical PC it is connected to via a switch, I see that it gives a VPN error. Then I go to the wizard and repeat the configuration. And it gives me an error on the internet, but it lights it up in green. Then I try to configure the VPN and it fails in the UDP connection and the direct HTTP connection. Can you think of what could be the problem?
I attached the configuration file for you to take a look ;).
All the best,
samuel

It will give you a green check for having an IP address. You have a static IP set so it will always pass this check.

Yes, you have no internet connection on the ethernet cable. Check the connection.

I also noticed that there is a cellular modem installed but it is not being used.
