[Resolved] Unable to parse data from service response.

I am trying to: Update WPML and related plugins

Link to a page where the issue can be seen: hidden link

I expected to see: Plugins updated

Instead, I got: Unable to parse data from service response.

I have already tried disabling the firewall plugin and it didn't help.

I have checked the server logs and the requests are not being blocked. Here is an example request with a 200 response (no response has 403):

86.234.4.110 - - [10/Oct/2023:09:12:49 +0200] "POST /wp-admin/admin-ajax.php HTTP/2.0" 200 36 "<em><u>hidden link</u></em>" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/117.0.0.0 Safari/537.36"

I also include a screen shot of the installer support page showing the error.

I just checked and this is happening for all my sites. It appears there is a major issue with your plugin update service.
