Hi! Not worked. What happens when i run yum command:
http://sng7.com/os/7.8/os/x86_64/repodata/repomd.xml: [Errno 14] curl#7 - “Failed to connect to 2606:4700:3036::ac43:cdf1: Network is unreachable”
Please help. This problem stoped my project.

FreePBX distro 15.0.17.63, Asterisk 16. Fresh install.

http://sng7.com/os/7.8/os/x86_64/repodata/repomd.xml: [Errno 14] curl#7 - “Failed to connect to 2606:4700:3036::ac43:cdf1: Network is unreachable”

OK, so sng7.com has both A and AAAA records:

curl preferred the IPv6 route, but something in your system doesn’t work properly for IPv6.

Possibly this will help:

Why yum resolve dl.google.com to an IPv6 address?

[yelaman]

This is what i get:

Thanks. But that didn’t solve.

[Stewart1 (Stewart)]

If IPv6 isn’t working on your network, you should try to force IPv4. Use ip_resolve=4

[yelaman]

[Stewart1 (Stewart)]

Confirm that your yum.conf doesn’t have both ip_resolve parameters – I have no idea what that would do.

I have no trouble accessing http://sng7.com/os/7.8/os/x86_64/repodata/repomd.xml from here, so there is likely something in your network config (probably router/firewall) that is preventing the IPv4 access from working. Running curl manually, along with tcpdump / Wireshark if needed, should let you see what is going wrong.
