Hello,
I would like to report an issue we are currently facing with WPML AMS / ATE communication.
We are seeing the following error repeated hundreds of times in our debug.log:

WPML: Failed to send site key to AMS: AMS API returned false

We have verified that all our sites are correctly registered in our WPML account with valid site keys:

DEV
STAGE
PROD

You can confirm this here:
https://wpml.org/account/sites/

To troubleshoot, we also deregistered and re-registered the sites, but the issue persists.

In addition, we consistently see the following errors in:
/wp-admin/admin.php?page=wpml-tm-ate-log

Event: ATE Server Communication

Description: Unable to authenticate

Extra data:

{
"url": "hidden link",
"requestArgs": { "method": "GET" },
"status": "auth_error"
}

This confirms that the WordPress sites are able to reach WPML servers, but authentication with AMS / ATE is failing.

Could you please:

check if there is any issue with our account or site keys on your side,

verify if authentication tokens need to be refreshed or reset,

and advise on how to stop these repeated AMS / ATE authentication failures?

Thank you in advance for your help.

Hi there,

We had an issue today with the ATE servers, that has been resolved since, if possible, please re send work to ATE and let me know your results.

The issue has been occurring for a few weeks, and even in the last few minutes, I can see the following messages in the debug.log file:

[02-Feb-2026 14:31:07 UTC] WPML: Failed to send site key to AMS: AMS API returned false
[02-Feb-2026 14:31:07 UTC] WPML: Direct site key sync failed, scheduled background task as fallback
[02-Feb-2026 14:32:20 UTC] WPML: Failed to send site key to AMS: AMS API returned false

Thank you for updating me!

Please contact your hosting provider and ask them to whitelist the following domains:
wpml.org
cdn.wpml.org
api.wpml.org
api.toolset.com
cloudfront.net

If that does not help, I would like to request temporary access (wp-admin and FTP) to your site to test the issue.
(preferably to a test site where the problem has been replicated if possible)

**Before we proceed It is necessary to take FULL BACKUP of your database and your website. Providing us with access, you agree that a backup has been taken **

I often use the Duplicator plugin for this purpose: http://wordpress.org/plugins/duplicator/
You will find the needed fields for this below the comment area when you log in to leave your next reply.
The information you enter is private which means only you and I have access to it.

NOTE: If access to the live site is not possible and the staging site does not exist please provide me with a duplicator package created with the duplicator plugin.

Thank you,
Bobby

Thank you for the access details!

I was able to get through server protection, but the wp-admin access is not working.

I'm left with 1 attempt.

2026/02/11 9:35:35 pm ATE Server Communication Unable to authenticate 0 0 {"url":"https:\/\/ate.wpml.org\/api\/wpml\/languages\/mappings","requestArgs":{"method":"GET"},"status":"auth_error"

API and Server connections check out OK.

Communication with wpml.org is OK and license is recognized.

However, the site is not connected to the ATE which is why you are getting this message.

Was this site recently migrated? If yes, what is the previous URL? (We will need to manually fix this from our side)

When I search using the user details I can see the following domains listed:

hidden link
hidden link
hidden link
hidden link

The behavior I am observing can sometimes be caused due to a migration and a 3rd party plugin blocking a WPML pop up that facilitates the migration.

The quickest way to resolve this would be testing with a minimal environment (deactivating 3rd party plugins)

Do you currently have a staging site we could perform this test with? If not I can migrate a copy of the site on our cloudways staging environment to further investigate.
