I believe the solution to this would be a fix in the Java Control Panel. When you open the page, you should see the Java icon pop up in the taskbar. Right click on it and select Control panel. Once you are in the Java Control Panel, select Advanced -> Security -> General and uncheck TLS 1.0.
Was this system recently upgraded from an older model (i.e., from a FAS3020 or FAS3050)? When systems are upgraded to a controller with a different CPU type or manufacturer (Intel to AMD), the binary compatible of Data ONTAP has to be installed as well. Even if the version of ONTAP doesn't change, ONTAP needs to be reinstalled because many of the JAVA and HTML pages installed to the root volume are coded/compiled for either the previous controller's CPU type. If the console is constantly spitting out messages about missing files in /etc, that's a good indication this is the problem.
Good news is, Data ONTAP 8 is CPU agnostic so this shouldn't be an issue anymore.
oops...i didn't see the date. But interestingly I had the same issue just before posting the solution here, I followed this KB article and fixed it. I just thought it will be helpful if I post the solution here.
