Nextcloud - "/well-known/caldav" issue

[jtippetts]

Hello I'm actually reposting this question that someone had a while back. It said the issue was resolved but I'm having the same error on a brand new install. I'm not on a VPS if that matters at all...

I need your help please with a setup warning in Nextcloud.
I have installed the contacts and calendar app.
And now I get the following warnings under Administration / Overview:

There are some warnings regarding your setup.

Your web server is not properly set up to resolve "/.well-known/caldav". Further information can be found in the documentation.
Your web server is not properly set up to resolve "/.well-known/carddav". Further information can be found in the documentation.

There is a link to the following documentation:
https://docs.nextcloud.com/server/18/admin_manual/issues/general_troubleshooting.html#service-discovery

I tried commenting out the lines referred to in the previous answer but I'm still showing the error after restarting nginx

@jtippetts Just to double check.. are you using Cloudron to deploy nextcloud ? Because cloudron does not use nginx to deploy nextcloud.

@girish Hello, yes I just installed Nextcloud from the app store in Cloudron.

@jtippetts Oh ok, so those URLs should work automatically on Cloudron.

• Can you first check what curl -v https://nextcloud.domain.com/.well-known/caldav returns from your PC/Mac ?
• If the above works, can you try curl -v https://nc.cloudron.space/.well-known/carddav in the app's web terminal ?

I suspect the first one works but the second one doesn't. Let's see...

@girish You're right. The error message persists but everything seems to sync fine once I set it all up. THANK YOU!

@jtippetts Yes, if the second one is failing, it's most likely because the server is unable to reach itself. Is this server in a home network?
