Ok. Worth a shot. The problem is usually like this: - site url in local.php - site url in apache - https/http redir fails - cache issue (needs rebuild) - hidden files not moved - causes error ---

I changed my domain in Configuraiton “Site URL”. Are you getting a mautic login prompt? If not then I think it’s the web server. Usually in either Nginx or Apache there is a Server Name field that you should change, too. That’s what I had to changed when I did it. Restore from backup and try again as your 3.1 upgrade failed. ---
