Proton lost me when I found out you can’t receive notifications from their app on a de-googled phone. Their app requires Google services for notifications. Since then I’ve moved to Tuta and am very happy with the service and notifications work. I mean how hard is it to set up a new email check every half hour in the app. What’s the point of private email when you have to run it on a spyware (Google) infested phone.

I found lots of useful information here: https://appelman.se/matrix-on-cloudflare/

Thanks for the reply. In the end I had to solve it by hosting the .well-known files on the main domain using Cloudflare Pages. I didn’t want the subdomain in the server name.

I have the same problem. Has anyone found a solution?
