I'm also having similar issues accessing gitlab.com with IceCat.
Installing the User Agent Switcher and setting to "Linux / Firefox 82"
fixed this for me.

For context I also tried starting IceCat up in safe mode and switching
tracking protection back to "standard", but no good. The issue appears
to be that Cloudflare are essentially blocking niche user agents.

Regards,
Ben

A workaround is setting the "User Agent" string to something CF likes, e.g.=
 like this:
qutebrowser --temp-basedir --set content.headers.user_agent 'Mozilla/5.0 (W=
indows NT 6.1; rv:60.0) Gecko/20100101 Firefox/60.0' https://gitlab.com/use=
rs/sign_in

Maybe the reason why the (very helpful) #qutebrowser folks can't
reproduce this, is because they use another qt version (qutebrowser uses
qtwebengine) and perhaps this sets user agent to a string that CF has
whitelisted.

I don't think there is much we could do here (besides updating qt and
mbakke has that in the pipeline, afaik).

I already contacted the people in the qutebrowser IRC. The bug persists
when I launch with no config (`qutebrowser --temp-basedir'), and they
could not reproduce the issue on the same version of qutebrowser I'm
using. I suspect it may be an issue with the guix version.
