It should be yellow if trying to connect and red if it cannot resolve. Do you see it or just blue?
Discussion
When connecting to my VPN it's blue
When I'm using Chinese net it's red.
I checked your website and I saw it was blocked.
So that's why I suggested this.
When nip05 is successful checking it becomes blue and connecting is yellow.
failed to check can be red and fail to connect with the server should be a different color to display I suggest.
one extra:
Where is the nip05?
Blue
