The issue was caused by my ISP, who was returning a search result while trying to connect to a non existing url (http://some.unknown1234xxx.test.aws). I solved it by running a VPN client , thus eliminating my ISP from the loop. All works now !

This was happening to me as well while trying to build it in a docker image. I didn't have a VPN client readily available.

My fix was changing the default DNS on my Mac from my ISP's to google's public DNS @ 8.8.8.8
