Just some thoughts PIG,
Have you tried, or can you, access your camera by IP address instead of URL to make the changes remotely?
Trying to access
http://mysite.verizon.net/pineisland/PineIslandGuy.jpg
gives:
Locked
The requested resource is currently locked. The lock must be released or proper identification given before the method can be applied.
Can you get in by trying
http://mysite.myfairpoint.net/ which gives a login screen
Trellix Login
Username xxxxxxx @myfairpoint.net
Password xxxxxx
use your Verizon username and Verizon password in place of the xxxxx.
