"FAILED: updating all.dnsomatic.com: authorization failed (HTTP/1.1 401 Unauthorized"

You'll need to check your user ID (= e-mail address) and password in the ddclient.conf file. The password must not contain special characters reserved for URL encoding.

I agree with rotblitz, I would check your password in the ddclient.conf file and make sure the password does not contain any special characters.

In addition to the above suggestions, please double check the server name, because I see this in the results:
```
FAILED:   updating all.dnsomatic.com: authorization failed (HTTP/1.1 401 Unauthorized 
```
The correct domain should be myip.dnsomatic.com. Please double check the config file running the following command:
```
sudo nano /etc/ddclient.conf
```
Then update the domain name and ensure that the username and password is correct with no special characters - only alphanumeric passwords are accepted. Also, note one of the comments in the URL rotblitz provided, to add apostrophe's before and after your password in the config file. This can be changed at https://dashboard.opendns.com/myaccount/password

Then restart the app:
```
sudo /etc/init.d/ddclient restart
```
We've received your support ticket and replied back with the same information, however feel free to reply back to this post with your results.

"The correct domain should be myip.dnsomatic.com."

Oops, I'm afraid this is a mistake. The domain/site myip.dnsomatic.com is for checking the IP address only, but all.dnsomatic.com is a pseudo-hostname to be used in updates to updates.dnsomatic.com.

http://myip.dnsomatic.com/

updates.dnsomatic.com/nic/update?hostname=all.dnsomatic.com

I realize this thread is old but OpenDNS now requires special characters in passwords. I used an asterisk (*) in my password and it worked for me.

Same here. It still fails if you use & though.

What information can you provide, so that we can provide help? "It does not work" is never ever a way to proceed...

How odd: I've received an e-mail saying there's another comment on this thread, but I go back here and it's not there. Anyway, the other comment suggests my previous comment was unclear. What I meant was, if I put an & in my password, I get the same 401 Unauthorized error that Anthony Honciano mentioned above. I have solved this by replacing the & with a *.

Well, my message went into "pending approval" status, therefore you didn't find it when you came back.
(Also this message may land in "pending approval" first, I only know after submitting it.)

Glad to hear that you could solve the problem.

A current problem is the failure of OpenDns with ddclient. I have managed to solve the problem in a not very decent way.

Something like that:
sudo nano /var/cache/ddclient/ddclient.cache

and add ip=0.0.0.0 at the end of the sequence of variables, just before your 'opendns_network_label'

Apparently, it doesn't work because that data is empty.

approximate content of ddclient.cache would this be

## ddclient-3.9.0
## last updated at Mon Nov 4 02:44:29 2019 (1572846269)
atime=0,backupmx=0,custom=0,host=lavelme,ip=0.0.0.0,mtime=1572845979,mx=,script=/nic/update,static=0,status=good,warned-min-error-interval=0,warned-min-interval=0,wildcard=0,wtime=30 lavelme

I hope it helps you

Hello all!

In response to https://support.opendns.com/hc/en-us/community/posts/220035467/comments/360000138283:

It didn't help for me.
My password is sixteen characters long, with small and capital letters and some numbers, as well as an asterisk at the end.

Getting this:

FAILED:   updating 'Home': authorization failed (HTTP/1.0 401 Unauthorized
FAILED:    date: Sun, 29 Dec 2019 16:51:42 GMT
FAILED:    server: opendns

FAILED:    x-xss-protection: 1; mode=block
FAILED:    x-ingress-point: lon
FAILED:    connection: close
FAILED:
FAILED:    badauth)

Running the ddclient on a CentOS 6-server

Not sure what else to try. Any advice?

How does your ddclient.conf file look like?

Yupp, forgot that. Sorry.

I based the config on info from https://support.opendns.com/hc/en-us/articles/227987727-Linux-IP-Updater-for-Dynamic-Networks.

This looks good. I ran out of ideas. Raise a support ticket, link “submit a request” above.

Ok, thanks for checking!

Late yesterday evening, I did some digging, turns out my router, an oldish Asus RT-N56U with custom ROM installed, has a dDNS-feature.

On a hunch I entered the OpenDNS-credentials etc, chose www.dnsomatic.com as the service provider and hit apply - and what do you know, it worked!
The router itself is now updating the WAN-IP to OpenDNS. So far all is A-okay!

Would have been nice to know though, just why it doesn't work for me using the ddclient...
Oh, well, I'll dig into that problem later, for now it works.

Thanks all for the hints, tips and tricks!

The problem looks like one I finally solved after much, much trouble, no thanks to the useless VIP support.

The single quotes around the password field are not ASCII, and if you copy/paste the code, it will fail. Replacing the quotes with normal text quotes will fix it. I reported this error today, although my experience with support leads me to believe it will not accomplish anything.
