@deximer Many thanks for your reply. I have used port 3122, and checked that it is open on the disk server. I also double-checked my gpg and ssh keys. Everything is in order. I have also installed portaina.io and find it very useful but it hasn’t helped me figure out what I’m doing wrong.
The bit I don’t understand is whether I should set up the identity “git” as a user. Typing git@[ip address] seems to me that the server should recognise git as an ordinary user. I have of course tried using the only two authorised users, i.e. admin and my own login. But I normally have admin disabled and wouldn’t use it normally. Just thought it was worth a try.
I have also changed my password to make sure I know that I am typing it correctly when prompted. I am sure it’s not the password that’s keeping me out though.
