I am having an issue with account registration on the phone, the account was setup and worked fine for a while but today all of a sudden the phone went offline and on the account registration page on the phone web interface the status says registration failure. I cross checked the password and register name all is correct & hasn't been changed. I tested with another account and it registered fine but when i tried my primary account it fails registration. Please assist i have attached a screenshot, thanking you in advance
