@zontreck Is your password accepted and there's just no data coming through or do you already fail to authenticate?
Are you using 2-factor-authentication with Nextcloud?

[zontreck]

Unsure if authentication is even succeeding. On the phone it says it fails to add the server. However the server does not have any useful information so I had to run a dump on the request coming from the phone.

@zontreck

• Are you using app passwords or plain ones?
• Did you use the specific URL provided under iOS/macOS CalDav address in the calendar app?

[zontreck]

I'm just using the same username and password i use to login to Nextcloud. And i tried both ways to connect it to nextcloud

http://cloud.example.com:2590/
http://cloud.example.com:2590/remote.php/dav/principals/users/exampleUser/

[zontreck]

After enabling SSL on the apache server the connection worked perfectly. This appears to be limited to non-HTTPS connections

[wiswedel]

Actually I had similar issues on my own phone just yesterday - turned out they only happened on 4G. Once I logged into my home wifi, everything worked as usual.

However, I'll close this issue since we both have either a solution or it's not Nextcloud-related after all.

[zontreck]

This is nextcloud related. Since its not properly responding when ssl is disabled on the server.

[zontreck]

@wiswedel can you please at least look into this because having to obtain an ssl certificate for my home personal cloud was not optimal but I did so just to test a theory. I CANNOT get dav to work without ssl

iOS 12 requires an SSL / TLS connection for CardDAV and CalDAV sync.

We should obviously add this information to the documentation.
