Gitahead Unable to fetch from 'origin' - invalid url, missing path

Question

I'm using git GUI GitAhead v2.5.8. I use https for git'ting.

I get the message

Unable to fetch from 'origin' - invalid url, missing path

when pulling or fetching from my repo. The config file is OK and the repo was already cloned from GitLab.:

[core]

repositoryformatversion = 0

filemode = true

bare = false

logallrefupdates = true

[remote "origin"]

url = https://gitlab.com/myproject/myrepo/

fetch = +refs/heads/:refs/remotes/origin/

[branch "master"]

remote = origin

merge = refs/heads/master

[pull]

rebase = true

[gui]

encoding = UTF-8

[credential]

helper = store

I can't realize what's going on.
