My team member cannot signup to gitlab "You are currently viewing from a blocked IP address or country"

I am currently based in Sofia, Bulgaria and my new team member is based in Tunisia.

I have invited her to a group, however, when she was trying to signup she got “You are currently viewing from a blocked IP address or country”.

She’s tried using a different browser and she doesn’t use any ad-blockers but the issue still persists.

Can someone please help us?

Thanks
