Describe the bug

After setting up a local environment running using the Docker instructions, and creating a new WordCamp and its site, I was unable to browse to the site.

Blocking: #777

To reproduce

Steps to reproduce the behavior:

1. Setup your local environment using Docker.
2. Create a new WordCamp at https://central.wordcamp.test/wp-admin/post-new.php?post_type=wordcamp. Mine was Ryan 2022.
3. Advance the WordCamp to a status of "Needs Site" and enter any required information.
4. Fill in the URL field (mine was https://ryan.wordcamp.test/2022/), check the box to Created site in network, and change the status to Needs Crowdsignal Account.
5. Add to my /etc/hosts file an entry for my WordCamp. Mine is

127.0.0.1 wordcamp.test central.wordcamp.test city.wordcamp.test ryan.wordcamp.test

6. Browse to https://wordcamp.test/wp-admin/network/sites.php and see the site.
7. Click on Dashboard under my new site: https://ryan.wordcamp.test/2022/wp-admin/. See the following error:

This page isn’t working

8. Clear all cookies following the instructions above.
9. Browse to https://ryan.wordcamp.test/2022/wp-admin/. Continue to see the error
10. Browse to https://ryan.wordcamp.test/2022/. Can see the new site's public pages without issue.

Attached is a zipped .HAR file.
