Actually I just noticed it’s probably not a syntax issue

```plaintext
SiteSetting.prometheus_trusted_ip_allowlist_regex="123.145.167.189"
NoMethodError: undefined method `prometheus_trusted_ip_allowlist_regex=' for #<Class:0x000055a8093e7dd8>

```

Maybe @sam can help with that. Or I’m really just making a mistake here. 🤔
