**Your software**
My Mautic version is: 3.1.2
My PHP version is: 7.3
My Database type and version is: 5.7
**Your problem**
Besides that Mautic seems to run without errors i find those logs below.
I run Mautic behind a Nginx reverse-proxy and have added
$\_SERVER[‘HTTPS’] = ‘on’;
to start of index.php of Mautic.
The SSL-Termination is done at the revprox.
These errors are showing in the log:
[2020-11-11 14:50:43] mautic.ERROR: Uncaught PHP Exception Symfony\Component\HttpKernel\Exception\BadRequestHttpException: “Untrusted Host “89.239.2.123”.” at /systems/mautic/htdocs/vendor/symfony/http-kernel/HttpKernel.php line 71 {“exception”:"[object] (Symfony\Component\HttpKernel\Exception\BadRequestHttpException(code: 0): Untrusted Host “89.239.2.123”. at /systems/mautic/htdocs/vendor/symfony/http-kernel/HttpKernel.php:71, Symfony\Component\HttpFoundation\Exception\SuspiciousOperationException(code: 0): Untrusted Host “89.239.2.123”. at /systems/mautic/htdocs/vendor/symfony/http-foundation/Request.php:1319)"}

❗ Ensure this IP belongs to you. It may be a true CORS request.
**If this ip belongs to you follow these steps:**
Did you setup CORS in the config section in Mautic? Either remove this feature or add the ip of your Ngnix proxy i.e. 89.239.2.123.
**You can alternatively change this in local.php:**
You probably have something like this in the local.php
` trusted_hosts: - "%domain%"`
either remove it or add the IP

Yes, the IP belongs to the Mautic reverse proxy. And i also setup CORS:
```
'cors_restrict_domains' => 1,
'cors_valid_domains' => array(
'0' => 'https://mautic.my.domain',
),
```
The URL [https://mautic.my.domain](https://mautic.my.domain) points to the abovie IP address 89.239.2.123 (of course this i anonymized and not my real address and name, as i do not want to post it here in public).
The trusted hosts is set to:
```
trusted_hosts' => array(
'0' => '.*\\.my\\.domain$'
),
```

Perfectly understandable. If you ever really need to you can use a PM. But in this case confirming you’ve checked it is enough.
What happens if you add the ip address to your CORS config?
