I needed to delete and recreate my pages project (as per guidelines in the discord) when moving from cloudflare managed build/deployments to my own gitlab ci via manual upload. After re-creating the project, my preview deploys seem to be encountering some SSL issues. I tried deploying another preview and this issue is not resolved.
I know this isn't an issue with my app, because before re-creating I was deploying previews on a test project just fine https://3bad9091.j-along-test.pages.dev/
