Relatively fresh deployment of Matomo 3.9.1 - the email reports contain the IP address of the server instead of the hostname:

We have multiple servers running behind a load balancer in AWS and have set things such as trusted hostnames in the config.ini.php file. We've followed the steps in this guide to implement load balancing: https://matomo.org/faq/new-to-piwik/faq_134/

I've also tried updating the piwikUrl row in the database however it just gets updated by itself to the IP address of one of the servers.

Happy to provide other information, just let me know.

@GavL89 I'll mark it as a duplicate of #11029

We also had other similar issues like #13176 and #13122 and I reckon we thought it was changed.

Is any of the trusted hostnames an IP? I'll create a comment in #11029

Thanks @tsteur - I've put a comment onto the other thread with some more information.
