Cannot load Wordpress Multisite after setting primary domain

Hi everyone.

I have a domain registered through route 53 and the DNS zones and wordpress multisite set up through Lightsail.

Everything was working until I went to change the primary domain, here https://lightsail.aws.amazon.com/ls/docs/en_us/articles/amazon-lightsail-define-the-primary-domain-for-your-wordpress-multisite

After that, navigating to the domain leads to a server not found page. I also can no longer load anything from the static IP address. Trying to navigate to the static IP address redirects to http://[domain].com/wp-signup.php?new=[static ip].nip.io which also does not load. If I try to use the Bitnami command to change the primary domain back to the static ip or [static ip].nip.io I get a "too many redirects" error.

I've double and triple checked and I'm almost positive I followed all the steps correctly. Has anyone else had this issue and know how to fix it?

Thank you!
