iOS: CalDav/CardDAV: domain daaccountvalidationdomain / error 100

Trying to set up CalDav on iOS 18. I downloaded the iOS configuration file and when trying to install it, it asks for a password. I entered the Nextcloud user password (no idea what other password it’s referring to), and I get “domain daaccountvalidationdomain / error 100.”

I am running Nextcloud as a TrueNAS scale app behind HAProxy.

The same here! Any hints?

Same here. Is there a Workaround or help?

Not sure if it helps with the error, but you can create an app password (Settings → Security in Nextcloud) and use that as a password. In fact that is even recommended to do.

This is also happening to me. My setup is Nextcloud running on TrueNAS. Nextcloud is using the TrueNAS’ default certificate (self-signed)

I found a hint here: https://github.com/nextcloud/all-in-one/discussions/5210

For me solved the following settings the issue.

Hope it helps.

iOS does not support self-signed certs anymore. So your issue is different.

Actually, I don’t think so. I can install my self-signed cert on my ios18.

Installing self-signed certs (from own CA) isn’t the same as accepting self-signed certs from arbitrary webserver.

See trouble with iOS18 e. g. at iOS 18 Bug -Certificate Trust Sett… | Apple Developer Forums
