Argo DialContext Error i/o timeout

#1

When trying to get Argo running, we hit the following error:

ERRO[0363] Unable to dial edge error="DialContext error: dial tcp 198.41.200.53:7844: i/o timeout"

I am presuming this is because cloudflared requires outbound connectivity to CloudFlare on port 7844. We wouldn’t allow this by default.

Is my supposition correct, and if so, is it documented anywhere exactly what the connectivity requirements are?

You are correct about port 7844. I can’t find any in-depth firewall configuration suggestions in the public documentation, but there is a reference to port 7844 here:
