Defguard enable to connect

[eayetsi]

I installed Defguard one script and tested connectivity. After hours, I tried to connect again after adding allowed ips. now the client does not even give me the "connect" button to connect.

It shows connected in the web-ui but nothing works

I used wireguard client and I was able to connect. But I will be happy to help me resolve the Defguard Client issue. I have installed it on Mabook ARM.

Hello @eayetsi,

Can you enter the location view of your Instance I marked on the screenshot and show us what's there?
