Continuation from the ticket at My IP address (behind NAT) is blocked · vercel · Discussion #7403 · GitHub

On my MacOS 14.5, the command traceroute nor tcptraceroute has -T switch. So here is
sudo tcptraceroute vercel.com 443

❯ sudo tcptraceroute vercel.com 443

Hi, @zbycz!

Welcome to the new platform, great to have you here :smiley:

Thanks for your patience with this! I’ll get your output sent internally and loop back as soon as I can.

Hi, @zbycz!

Hope you’re well, I got an update internally.

According to the TCP traceroute output, it appears that you successfully connected to the Global Accelerator endpoint IP address “76.76.21.9”, which maps to the correct endpoint.

But we found that while the Global Accelerator responds to ICMP pings, it does not respond to ICMP-based traceroutes. To better test connectivity between the client and the Global Accelerator endpoint, could you use a TCP-based traceroute?

For more information, you can refer to this documentation.

Here is the command as you wrote:

sudo traceroute -T -p 443 vercel.com
