A problem that has followed me around the last two jobs: I can’t access the git server when I’m tethered using ssh authentication. But cloning via https is fine… it feels like ports are being blocked by the VPN.

So it seems to be my EE phone not working correctly over IPv6, or rather not switching back to IPv4 correctly. And the fix is to create another APN with only IPv4 enabled.

You don’t have to fill in all the fields.

Name			ee1
APN			everywhere
MCC			234
MNC			30
Authentication type	PAP
APN type		default,supl
APN protocol		IPv4
APN roaming protocol	IPv4
Bearer			Unspecified
