Hello,
when i adding a new Davdroid account (Version of Davdroid: 1.6.4-gplay) with Radicale Verion: 2.1.2 i cant add a new Davdroid account. The old working account is on a Raspberrypi 3 with Radicale Verion: 1.1.1
I use this Server-URL for my new Davdroid account with Radicale Verion: 2.1.2:
https://NEWIP:PORT
A Radicale server was found but Davdroid loading… and loading… and loading…
Here is a Picture from it:

Here is the davdroid log:

Here is the DAVdroid 1.6.4-gplay debug info were i can access:
https://friendpaste.com/38sPDXt7mfRyBbZ5rJdqce
The Radicale server works fine with Thunderbird + Lightning.
What is the Problem?

DAVdroid waits for a certificate confirmation. Normally, the confirmation dialog should appear directly and there should be a notification. Did you turn off notifications?
Can you try to reset the stored certificates (in DAVdroid / Settings), restart DAVdroid (terminate it from the task manager) then try again?
Hi, thanks for the fast reply!!
I have reset the stored certificates many times and the Popup with the certificate asking comes up when i start adding the newip and i have comfirmed it (its a Let’s Encrypt certificate)
But the problem is the same 
@kralle Is this problem reproducible with another device? In this case, I could try myself if you can provide a test account.
@rfc2822 i can check it with another device later. I reply when i check it 
The URL:
https://NEWIP:PORT
ist correct or?
@kralle For Radicale, see https://davdroid.bitfire.at/configuration/radicale/, but it also depends on your setup.
@rfc2822 I testet it with 2 devices:
InewV3 with Android 6.0.1 and DAVdroid 1.6.4-ose --> [devide is rooted)
I use: https://NEWIP:PORT —> i testet it more then 10 times and it works all fine!
Moto G (1. Generation) with Android 7.1.2 (LineageOS) and DAVdroid 1.6.4-ose --> [devide is rooted)
i use the same setting:
https://NEWIP:PORT —> i testet it more then 10 times and it dont work
Is the problem Andoid 7.x (7.2.1) ?
@kralle DAVdroid has successfully been tested with Android 7.x. I guess it’s something device-specific
@rfc2822 Okay , but 2 differnt devices with Android 7.1.2 have the same Problem?
I testet some other CalDav apps from google PlayStore all i testet works fine, but DAVdroid dont works with the same settings/config
Reinstall of DAVdroid also dont work
We have fixed a potential race condition which could be the cause of your problem. I’ll send you an APK over email soon
@rfc2822 thats sound good 
@kralle Thanks for your feedback. Should be fixed with cert4android/2303f98d.
