Can't log into ex3700 AP

I have my EX3700 set in AP mode and it is working fine. However I can not get the access screen anymore to log into the AP.

It has a different SSID from the main router and I have my laptop connected to the AP but its not working. If I try and use www.Mywifiext.com it says I am not connected to the Internet but of course I am. I checked the IP address in the main router for the AP and it shows  192.168.0.165 but that does not work either. I have tired clearing browers and different web browsers with no luck. Any suggestions?  I really would hate to do a factory reset as my security cameras are linked to this AP and I would have to remove them all and do a new camera install if I delete the stored info.
