This is strange. I haven't encountered this issue before.
I do have a static IP. I'm comparing the records to the ones that are working on Namecheap. The A Record IP address is the same, and so is the AAAA Record. So I'm not sure what I could change.
Currently the error I'm getting when I navigate to the website is that there is a self-signed security certificate.
I just tried re-establishing the domain on Cloudron and refreshing the certificates, but we are still stuck at the "Waiting for propagation" stage when installing. In my browser, the website is on the page that says "You are seeing this page because the DNS record of magicmountaintalks.org is set to this server's IP but Cloudron has no app configured for this domain."
Update: After a few minutes of trying the install, it reverts back to the "The certificate is not trusted because it is self-signed" error. And if I refresh the certificates, I can access the installed app, but the Cloudron backend is treating the install as having failed, so I can't do any administrative tasks. That seems to me like more likely a Cloudron issue than Namecheap, since the site is accessible.
Is there anything else you can recommend I try?
Thank you.
