MacOS – No SSH connection possible over Wi-Fi

macosNetworksshwifi

I have a MacBook Pro from 2014 running macOS Mojave. I cannot SSH into a remote server, use git over SSH or use the Mac App Store while connected to my Wi-Fi at home. Some of my mail accounts seem to have a problem, others work.

There is no problem with other devices, there is no problem if I am connected over Ethernet, there is no problem if I am connected via a different Wi-Fi, there is no problem if I use my university VPN via Wi-Fi, and there is no problem if I am running Ubuntu via USB.

The problem seems to be a specific combination from Home Wi-Fi and my macOS. I don't really want to reinstall my OS, and I don't have a single clue what I can do or try.

DNS-Servers are:

  • 8.8.8.8

and

  • 8.8.4.4

for IPv4, and

  • 2001:4860:4860::8888

  • 2001:4860:4860::8844

for IPv6.

This could be due to network segmentation.

What type of gateway/router are you using?

Is it possible that you are connecting to a guest type network, or that the gateway has a network segmentation feature which is turned on?
