Connecting to the readyNAS admin page... -repeatedly

Hi,

Starting today, I continually get "connecting to the readynas admin page" when I try and log into Readynas as an administrator.

Turned off anti-virus

Have rebooted several times

running 6.6.1

Although it will load admin page eventually, any attempts to look at apps, results in a reload page.

Not doing anything results in a reload after a minute or so

Can't get far enough to try and delete snapshots (based on other posts)

Was able to get to logs once, but no errors

Haven't loaded any new apps recently, and can't seem to get far enough to turn any of the existing ones off without a reload page

Tried multiple browsers, same issue

Drives seem operational, and no red lights.

Attempting to use plex to stream movies works, but intermittently.

Almost 50% volume free

Have recently completed a rather large PC backup via acronis 2017 which completed successfully.

Any thoughts on this?
