Secure Connection Failed or 404 page not found. Cannot access UPS.

I have several of the Smart UPS-3000 models in 4 offices. I have one that all of a sudden is giving me these errors when i try to connect via web interface. I have googled this to death and tried all kinds of stuff. I just did a reset and no change. I also unseated the card and that didnt help either. It is pingable and I get cert errors like normal when accessing it but then it just fails. Ive tried on several browsers even old ones to see if it was a new SSL issue. Any help would be greatly appreciated. Thanks

Thought i would update. I just did a full reset on the network card and started re configuring. I got about half way through and I was updating a page and it threw me out with a

@parkcitygolfer 

1. What is the model of the network card and what firmware is it running? 
2. Can you SSH or telnet to the card?
3. Is the card local or are you connecting from a remote site?

Not sure of the firmware

Yes i can ssh to it. Telnet hits it too. I can also ping it. It will stay up for days if i dont make any changes but once i turn on NTP or change the name it instantly starts throwing that error.

This is a local card on my network.

Thanks

Logged into the card via FTP

1. changed to the ssl directory
2. del defaultcert.p15
3. quit

Logged into the card via Telnet and reboot the card.

Once the card has rebooted upgrade the firmware to 7.0.4
