Can't add vega 50 europa "please recheck IP or network connectivity.."

Hi, I am setting up a sangoma vega 50 europa, and I can connect to it from my linux ssh client using the command: ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 -oHostKeyAlgorithms=+ssh-dss -c aes256-cbc [email protected]

So I know for fact that ssh is enabled on vega and working.

But when I try to add it to Vega Gateway Management of the FreePBX , it says this error:

Is this vega model not supported on Asterisk 20? or I need to tweak something in order to add it?

In the description says: “The FreePBX Vega Gateway Manager allows easy configuration, monitoring, and integration of all models of Vega gateways.
FreePBX polls every configured Vega gateway for status updates according to the timing of the VEGA_CACHE_EXPIRE interval.”

Thanks!
