Error accessing admin page (the requested URL could not be retrieved)

Hello ReadyNAS experts

Unit: RN102

Firmware: 6.9.5

I've had a RN102 for several years now, been rock solid in terms of reliability and such except for the odd hiccups during a firmware upgrade or two.

Anyway, my latest issue is very puzzling. I noticed it today when I could not get into PLEX server (which is on the RN102) on any of my devices.

Troubleshooting steps I've done:

1) RAIDar (latest version) can scan and detect my NAS with no issues. System shows healthy. IP address shows correctly, no diagnostic errors, etc. However I cannot access my admin page. It times out with the generic Windows error "The requested URL could not be retrieved."

2) I can also see my NAS via my ReadyCLOUD account and all the files are there. I can also access all my NAS folders via my Windows laptop.

The only thing I cant do is get into my admin interface :( and PLEX isn't working possibly because the app must be disabled somehow?

3) I did a clean power down and reboot. System came up fine but did not fix the admin page issue.

4) I did a OS reinstall via the boot menu. Same result as 3) above.

5) I extracted system logs from RAIDar and tried to posted it here but apparently I can't attach a large zip file. So I just posted the output of the RAIDar screen after scan and detection of the NAS.

I am hoping someone can figure out what might be causing this to happen, and help me to get into the admin level again.

Thank you!!
