Resident ssh keys

[mrwsl]

I'm using a resident ssh key with my repos and on the command line git is working fine. When I open a directory in Gittyup and try to fetch, the nitrokey (on which the key resides on) lights up and I can touch to confirm. After that Gittyup complains with the message Unable to fetch from 'origin' - Failed to retrieve list of SSH authentication methods: Failed getting response. Has anyone a working set up with Gittyup and resident ssh keys?
