Bad authentication

[flixxx]

Trying to setup ddns-updater with my provider dynu
logs pulls the right info (current ip, ip logged on their site, domain, etc..)
when it comes time to update it, the following error;
ERROR bad authentication

I tried using my password, ip updater password, md5 hashed password.

I've been messing around, tested dynu's api and my information works properly. I believe ddns-updater may not be sending the right formatting.
how can we check what it sends to dynu? Is there a verbose log available.

Try LOG_LEVEL=debug it should log all requests and responses

Hello, did you have time to debug it? Thanks!

I have the same problem.
Tried both user and email address as username.
The debug log shows the following:

2022/12/03 14:11:56 INFO Updating record [domain: MYDOMAIN.com | host: MYHOST | provider: dynu | ip: ipv4] to use 123.191.135.321

I solved this way:
my old config was

    {
      "provider": "dynu",
      "domain": "mydomain.com",
      "host": "myhost",
      "username": "myusername",
      "password": "mypassword",
      "ip_version": "ipv4",
      "provider_ip": true
    }

I changed to:

    {
      "provider": "dynu",
      "domain": "myhost.mydomain.com",
      "host": "@",
      "username": "myusername",
      "password": "mypassword",
      "ip_version": "ipv4",
      "provider_ip": true
    }

now it works but I suppose it's only a workaround (maybe the problem is the "alias" handling?)

Awesome that helped quite a bit. Also sorry for the mega delay.
