Remote viewing error

I cannot seem to get remote viewing to work. I can stream to my iPhone when on Wi-Fi.

I have port 8089 open and forwarded to the Channels server in my hardware firewall. Just to be safe, I opened up the same port in ufw on the Ubuntu server.

Attached is the error I am getting. Thanks for any help.

There's some error on the server. Check the dvr logs via the web UI. Could be a permissions or disk issue

Thanks, I think it was a permissions issue. I just wiped out the existing install and re-installed it. Even though the web control panel is spinning on "requesting https certificate" the remote viewing over cellular appears to be working this time.
