Cloudflared tunnel to edge tcp port suggestion

cloudflared argo tunnel client use tcp port :7844 to cloudflare edge ,the port is often filter by middle security device or firewall . If this port is well known or universal ,such as 443 ,110 , everything will be easier much.

Sadly it is not possible, and no plans on changing the port too.

Open your security device or firewall to establish port 7844.

Thanks for reply. Change servic port for argo is diffcult ,maybe listening mutli port will make service more robust because most small business company rent office rome and firewall dev is managed by Building Property management department and hard to communicate. Anyway ,thanks for help.
