Caldav Setup fail on iphone 11 Max Pro

Hello,

we have some problem to setup a caldav account (SSL) on an iphone 11. We have an error and cannot connect to the caldav server.

on some older iphone, with the same account, we don't have the problem.

Any idea ?

SSL error with car play I am having CarPlay issues. I get an error message on my car: "An SSL error has occurred and a secure connection to server cannot be made." My phone will get the same error message. My phone is an 11 Pro Max and it's updated to 14.7.1 Is it the software? The phone? The car? Same thing happens with my husband’s phone while in the car - it’s an iPhone 8. I have OnStar and it’s WiFi. Help!

iPhone 4 not connecting to iCloud Hello - I have an old iPhone 4 I am trying to see if I can use for a specific app. I have and iCould account an it can see all of my newer devices, but not this old phone. I was hoping to connect to the App Store to download any apps to see if they work on the iPhone 4. And sync some old photos on this old phone that are not anywhere else right now. When using my current iCould credentials on this phone I am getting this error... "Verification failed... the certification server is invalid... you might be connecting to pretending to be "setup.icould.com..." (that's the summary) I am the original owner of this old phone and the phone originally connected to iCloud. I am connected to WIFI but not cellular. iOS 7.1.2

Unable to deploy Mobile Config for Active Sync on iOS 13.4.1 I'm trying to deploy a mobile configuration for a number of iPhones. The mobile configuration only includes PKCS12 for the client certificate authentication and the configuration of the MS Exchange Active Sync Server. I have an older ".mobileconfig", we've previously used and I have one with the same data, but generated by the current "Apple Configurator 2" from the App Store. The old.mobileconfig crashes without any further info, on the last step, after the user password for the Active Sync has been entered on iOS 13.4.1 but works perfectly fine on iOS 13.2.2 (both iPhone SE). With the new.mobileconfig, the setup finishes just fine and the profile is set up on the client, but it fails to connect to the sync server with the client certificate, both on iOS 13.4.1 and iOS 13.2.2. Upload for "Additional Text" keeps failing for me on here, so I'll attach a redacted version of both configuration files like so: old.mobileconfig: https://pastebin.com/X8Q0U90M new.mobileconfig: https://pastebin.com/bLs2wBcS My patience grows thin with this setup, so I am asking for help here. What is the issue with my mobileconfigs, how can I correctly generate/adjust the mobileconfig to have our iPhones connect to our Active Sync server with client certificate authentication?
