Unable to login to nextcloud via browser after initial setup


I’m new to Nextcloud and ubuntu servers in general, but have just setup my Nextcloud box. It booted it for the first time and see the startup message prompting me to enter my login credentials on screen (via HDMI to TV.)

The problem I am encountering is that when I followed the Netxtcloud directions about connecting to the lettter and trying the guide found at: https://insights.ubuntu.com/2016/09/27/first-setup-of-my-nextcloud-box/ I was still unable to login using my browser to Nextcloud, I am on the LAN with the box connected directly to the same router. I am also unable to use putty to connect.

None of the support tickets here appear to address this issue specifically that I have found to work, and now when I reboot I see the following error at bootup (again, via HDMI):

ubuntu-standard login: audit printk limit exceeded

I am attempting to login via firefox on windows 10, without a VPN or proxy, and am at a loss as to how to resolve this issue. Any help would be greatly appreciated.
