Hi there,
Cloudron v9 is amazing, and I really like the new interface.
However, I believe I have found a bug. I have created a test instance on AWS. When I add a domain for which the DNS is on Cloudflare, I cannot enable the proxying option (see error).
When I uncheck the "enable proxying" box, the domain gets added. I have tested this with multiple domains, but the result is the same.
