cannot access dashboard..ERR_EMPTY_RESPONSE

[newowner]

I am new homeowner to existing system... password was left to us by previous owner so we have been using for a year with original setup.

I cannot access dashboard from PC or mobile.  I cannot update any firmware because I cannot access dashboard.

R510... lights are working fine

Default IP address: 192.168.0.1   however, I had to do an arp -a CMD to find out connected IP addresses and find correct one.  I get to the admin/login.jsp screen to enter my login and password and this is the error I get, using admin and sp-admin as stated on the unit, also with the username and password I have been using for the past year...and the admin Lennar username and password that is on a printed sticker on the back of the device.

Thank you for assistance
