Self-hosted runner configuration timeout on connection to https://pipelines.actions.githubusercontent.com

Hi,

I’m trying to create a self-hosted Linux runner. Network my VM is in is behind a firewall. I’ve created necessary FW rules (port 443 open for outgoing connections) for addresses listed on https://api.github.com/meta.
I’ve successfully downloaded latest runner package, but I’m stuck on configuration (Authentication step).
The problem is that I’m not able to connect to https://pipelines.actions.githubusercontent.com (HTTP request timeout).

When I curl the address, it resolves to 13.107.43.16. The problem is that this IP is not in any subnet listed in Meta.
Is it possible that the metadata is outdated? If yes, what subnet should I add to my firewall?
If metadata is fine, then any ideas what might the problem be?

Thanks in advance.
BR,
Bartek
