Balance 310 running 5.4.9 build 1564
WAN1: DDNS domain x.changeip.net update failed. Authentication error. (Error code: 2)
I have re-entered both the username and the password.
I have used the same credentials to logon to https://www.changeip.com/accounts/ddnsupdates.php without any error.
The Dynamic DNS Update History there is empty.
What does Authentication error. (Error code: 2) mean for the changeip.com service?
And/or how to fix this error?
