setsockopt IPV6_TCLASS 8: Operation not permitted

Please use the following bug reporting template to help produce actionable and reproducible issues. Please try to ensure that the reproduction is minimal so that the team can go through more bugs!

A brief description
git fetch in IPv6 env now has this warning:
"setsockopt IPV6_TCLASS 8: Operation not permitted"
(but git fetch command itself eventually finishes correctly)

Expected results
the setsockopt() function should succeed without warnings.

Actual results (with terminal output if applicable)

$ git fetch; echo $?
setsockopt IPV6_TCLASS 8: Operation not permitted:
0
$ git fetch -4; echo $?
0
$ git fetch -6; echo $?
setsockopt IPV6_TCLASS 8: Operation not permitted:
0

Your Windows build number
Version 1703 (OS Build 15063.13)
git version <IP_ADDRESS>5.gb14f27f91
(PS: I did not see this issue before I upgraded to the Creators Update).

Steps / All commands required to reproduce the error from a brand new installation
. make sure the Windows system is in a working ipv6 environment
. clone a git repo
. fetch the repo

Strace of the failing command

$ strace git fetch
