Issues with IPv6 using Git

Hi when I use Git with my Bitbucket account, my system will hang when doing a Git push. I initially opened a bug with Bitbucket, they looked into this and said my IP6 is probably not configured correctly.

I was able to do the ‘Git push’ over IP4, and I got a freshly install openSUSE TW, so how can I track this problem with IP6 not working with Bitbucket and get it corrected. Disabling IP6 is not an option I to use.

I see both IP4 and IP6 for my Internet “enp37so”

Looks like my routes are defined for IP4 and IP6.
