Hello, dear friends!
Here is the right command: ont tr069-server-profile add
example: ont tr069-server-profile add profile-id 2 url www.huawei.com user hw huawei auth-realm auth


So please use this command to create the correct profile and bind again.
1. Some ONT have opened the Password complex check function: so if you create the same profile like step2 but still get the ONU return error, you can change the password in according with these requests and test again:
