Ipv6 not working

[franz_see]

When I do wget, it hangs

i.e.

 wget -v https://gems.hashicorp.com/specs.4.8.gz                                                                                                                                                                           ✔

If i force ipv4, it seems to work

wget -v -4 https://gems.hashicorp.com/specs.4.8.gz                                                                                                                                                         INT ✘  2m 45s 

This seems to be causing issues with other applications (like my vagrant)

vagrant up                                                                                                                                                                      ✔ 
Installing plugin vagrant-bindfs
Vagrant failed to initialize at a very early stage:

Vagrant failed to load a configured plugin source. This can be caused
by a variety of issues including: transient connectivity issues, proxy
filtering rejecting access to a configured plugin source, or a configured
plugin source not responding correctly. Please review the error message
below to help resolve the issue:

How do i force all network connections to use ipv4 only?

Thanks

You can:

• disable IPV6 in your router config

• You can disable via GRUB as follows:

  • Execute:

    sudo nano --backup /etc/default/grub
    

  • Search for the line containing:

    GRUB_CMDLINE_LINUX=
    

  • before the last " on that line, add a space and copy-paste this after the space, before the quotiation mark:

    ipv6.disable=1
    

  • Ctrl+X Enter Y to save

  • Execute:

    sudo update-grub
    

  • reboot

• You can also disable IPV6 in the individual Network Manager configurations.
