In the UK and have a VirginMedia Hub5 (OEM Sagemcom). I have am Asus RT-AC86U connected to it as a secondary router that I want to run IPvanish VPN on that I can set to the US and have my Roku stream from US sources that are otherwise unavailable here.
Followed all instructions, installed .ovpn and crt files, double checked login and password, but it won’t connect. Checking the system log I get “write udp: address family not supported by protocol (code=97)”
What’s going on and how do I configure this to work?
So ultimately the solution was that the ISP was blocking the domain IPvanish.com . Once I added it to safe sites and the VPN popped to life.
The “address family not supported by protocol” error usually indicates that the OpenVPN client is attempting to use an unsupported version of the Internet Protocol (IPv4 or IPv6) for the connection.
Here are a few steps you can take to try to resolve the issue:
Check the protocol settings in the OpenVPN client configuration file (.ovpn) and make sure they are set to the correct protocol for your network. You can try changing the “proto” setting to “udp4” or “tcp4” to force the client to use IPv4.
Check your router settings and make sure that IPv4 is enabled and supported. Some routers may disable IPv4 by default and only support IPv6.
Check if there are any firmware updates available for your router, as these may include bug fixes or feature enhancements that could help resolve the issue.
Try using a different VPN service or client to see if the issue is specific to IPVanish or the OpenVPN client.
If none of the above steps work, you may need to contact IPVanish support or ASUS support for further assistance with troubleshooting the issue.
