Error After Renew certificate ADFS 3.0–This page cannot be displayed

First lets go over the correct steps to renew the Certificate

Step1: Check the current signing certificates:

• Open ADFS  PowerShell command window, and run the following command:

Get-ADFSCertificate –CertificateType token-signing

• If you only see one certificate, and the NotAfter date is within 5 days, you need to generate a new certificate.

Srep:2 Renew the token signing certificate manually:

• To generate a new certificate, execute the following command

Update-ADFSCertificate –CertificateType token-signing

• Verify the update by running the following command again:

Get-ADFSCertificate –CertificateType token-signing

Step 3: Update the new token signing certificates for the Office 365 trust

• Run:

Connect-MsolService

• Enter the Office 365 Global Admin credentials
• Run:

Update-MSOLFederatedDomain –DomainName “Domain.com”

STEP 4:Check if the certificate is updated correctly

• Open ADFS  PowerShell command window, and run the following command:

Get-AdfsSslCertificate

• Look at the value: CertifiacteHash
• Check that the CertifiacteHash is the same as the thumbprint of the new certificate and not the old one

• If the thumbprint is not the same or you see only one cert and not two run the following:

Set-AdfsSslCertificate  -thumbprint “the new thumbprint”

• Run:

Get-AdfsSslCertificate

Check that the CertifiacteHash is correct.

Go over step 3 again (Update-MSOLFederatedDomain –DomainName “Domain.com”)

Good luck
