Ping Status for
http://cdn.mmoui.com/: 200 tries to send a ping (a short attempt to see if the address exists) to the ESOUI websites for Minion and fails.
Did you try point 13. from the troubleshooting guide

already as it often is the cause of that problem!
It could be that your ISP internet IP is blocked by cloudflare (a website that checks the traffic for several other websites like esoui/minion and protects it).
Please reach out to Dolby via private message and tell him your IP address of your Internet connection so he can check if it is blocked at cloudflare.
