I have Jenkins running on Ubuntu hosted on AWS. I can access the setup wizard; the problem I am having occurs after entering my admin password then proceeding to install the suggested plugins. I get an unable to connect to Jenkins message. Please, I need help on how to resolve this issue. I have spent hours trying to get this resolved by following suggested solutions but to no avail. Thanks
