A revocation check could not be performed while accesing RDS App

while configuring RDS and accessing RDS App, I got below screen, though this is not so critical, but my clean users do not want this extra click and see this message.
why this comes is, the machine can not verify the CRL (certification revocation list) URL, so can not verify if the cert is valid or not.


to over come this, you need to configure below in IE

·  Select Start»Control Panel.

·  Double-click Internet Options.

·  Select the Advanced tab.

·  In the Security section, uncheck the Check for publisher's certificate revocation option.

after this also I got same message from another machine.
try below
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Terminal Server Client\ CertChainRevocationCheck value 0


after this also, it did not work in another machine.
I did below


Run this command on Cmd as administrator:

reg add "HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client" /v "AuthenticationLevelOverride" /t "REG_DWORD" /d 0 /f

hope this will help.
