No data being sent to Google Aanlytics

After not having any luck with a GA4 tag, I decided to "downgrade" and create a Universal Analytics tag instead. When using the Tag Assistant Chrome extension, it's giving the errror `No HTTP response detected`, which is summarized below.

```
Missing HTTP Response denotes that, while the Google Analytics code was detected in the page source, the script itself did not execute. Each time the Google Analytics script executes, we expect an HTTP Response carrying the tracking request to Google’s servers.
This means that the Google Analytics code is not implemented properly on the page and no data will be collected.
Recommended Action: Reinstall the Google Analytics snippet by removing the current iteration, copy a new version from the Analytics interface, and insert that version into the site.
```

I'm not seeing any errors in the docker container and the script is in the `head` tag of the HTML body (and being detected by the extension). We're running CKAN 2.9.
