Checking the environment variables and also HTTP configuration options does not reveal something. Is there a way to do this?
There are situations where upgrade git or where IPV6 is running but not working as expected, for example, under Windows Linux subsystem, my solutions is simple: just add the git/httpb/ssh IPV4 location on /etc/hosts.
Use host
to get the IPV4 address and append it to /etc/hosts with name for your own use, for example, 1.1.1.1 git4.server.com
