To add cipher suites, either deploy a group policy or use local group policy as described in Configuring TLS Cipher Suite Order by using Group Policy.Īfter you run Enable-TlsCipherSuite, you can verify the order of the cipher suites by running Get-TlsCipherSuite. Resolution Windows 10Įven after you upgrade to TLS 1.2, it's important to make sure that the cipher suites settings match Azure Front Door requirements, because Microsoft 365 and Azure Front Door provide slightly different support for cipher suites.įor TLS 1.2, the following cipher suites are supported by Azure Front Door: OS doesn't have TLS 1.2 enabled SymptomĪuthentication issues occur in older operating systems and browsers that don’t have TLS 1.2 enabled, or in specific network configurations and proxy settings that force legacy TLS protocols.

If neither of these suggestions pan out, open a DTS tech support incident and I’ll take an in-depth look at your issue in that context.As previously communicated in the Microsoft 365 Admin Center (for example, communication MC240160 in February 2021), we're moving all online services to Transport Layer Security (TLS) 1.2+. I recommend that you use that code to set up your keychain items. I posted some code showing how to do this on this thread. When putting credentials in the keychain, it’s easy to get confused. If you want your server to work with Personal VPN, you’ll have to get it a system-trusted certificate. Personal VPN does not let you customise server trust evaluation. If it doesn’t, you have server trust evaluation problems. With regards server trust evaluation, does you configuration profile contain a root certificate ( ) payload? If so, remove that payload and see if it still connects. There are two common causes of problems like this: However, when trying out through code, I get an error … Getting a configuration profile working is an important first step. I'm able to connect to the VPN using the VPN Profile.Įxcellent news. To rule out configuration / server issue, I first created a VPN profile and tried connecting to the VPN using it. ![]()
