Hi!
I'm developing my MAUI app and testing it on my iOS device via Visual Studio 2022 (Version 17.7.6). But suddenly I've lost my sync with my developer apple account. I've tried on other PC on the same network and It works properly, but on my device, when adding my developer account I get this log error:
There was an error while syncing the syncing identities information, please check the logs.
Xamarin.Messaging.IDB.AppleProvisioningManager Error: 0 : System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.

Via referring to Error while syncing Apple provisioning profiles. This error should be due to VS component indeed or version lagging.
Using Visual Studio Installer to update, does this issue still appear after updating Visual Studio?
I've installed the lastest version of VS and the problem still the same. Also tried deleting “%LOCALAPPDATA%\Xamarin\iOS\Provisioning” and adding the Apple Account again, and still the problem.

The remote certificate is invalid according to the validation procedure.
This error means that the existing certificate doesn't match the Provisioning profile.
Do you enable some capabilities for your app? such as adding iCloud entitlement?
Do you have the same issue when building an empty Xamarin.Forms app on your physical iOS devices?
What iOS device are you testing on?

@Wenyan Zhang (Shanghai Wicresoft Co,.Ltd.) Thank you for your answer, but this is not the problem, my Apple Certificates are OK, I've tried other machine, same network and It works perfect with those apple certificates.
I'm afraid the message "The remote certificate is invalid according to the validation procedure" refers to the SSL/TLS certificate, not the Apple developer certificates...
@Nithin Sri Thank you for your answer.
I'm on a Windows machine using the latest Visual Studio Version (Version 17.7.6). The problem is when adding my developer account, certificates are not loading (sometimes get same error when adding account).
Points 1and 2 checked. Point 3 not applied cause I'm not at this point. Tried point 4 (I'm on windows), and in chrome and edge, SSL apple certificate is OK.
Tried point 5, didn't work. 6 and 7 same result...
Add an snap of my problem:
From the screenshot, your apple developer account looks like an enterprise account, right? Do you click the Sign in with an enterprise account hyperlink and enter your credentials when adding this account?
In addition, is it possible for you to export the iOS certificate from your other work-well machines and then import the certificate to your current machine? (I mean skip sending request progress)
Also, please check if you have set up a network firewall that would cause this request to be blocked.
Yes, it's an enterprise account and I signed in with this option.
Yes, I exported certificates from other work-well machines, but this is not the solution I'm looking for because It must work on my machine...
I've check network firewall, but it's not seems to be the problem... (it's the same conf on work-well machines) but what kind of request should I check on firewall?
Do you try removing the Apple account and logging again? After clicking the "OK" button (as shown in the screenshot), there is a button named "Import Certificate", could you import your iOS development certificate?
For this request error issue that was thrown by VS, it's recommended that you report a problem with VS, see Report a problem with Visual Studio - Visual Studio (Windows) | Microsoft Learn
Yes, I've tried removing my apple account and adding again, nothing happened. And I've imported manually my certificate, but it should work the other way like It worked a few days ago and on other machines.
If so, please report a problem with VS, see Report a problem with Visual Studio - Visual Studio (Windows) | Microsoft Learn
I'm afraid this is a company firewall problem... could you mind provide me the URL's that Visual Studio are calling in order to create an exception on my firewall?

I have the same symptoms. I think Visual Studio is reaching out to developerservices2.apple.com during provisioning.
