Hello together,

if the ssl inspection is turned on, no more windows updates can be executed on the clients. I have already read that it´s a certificate problem and that you have to exclude the windows update domains from the ssl inspection. I have already done that, but unfortunately it has brought nothing. I excluded the following domains from SSL inspection:

windowsupdate.microsoft.com 

update.microsoft.com 

download.windowsupdate.com 

redir.metaservices.microsoft.com 

images.metaservices.microsoft.com 

c.microsoft.com 

download.windowsupdate.com 

wustat.windows.com 

crl.microsoft.com


Can anyone help me with this problem?

Thanks!

    Hi @Spielkultur_1

    Can you help to check if there is any other domain related to Microsoft in USG Certificate Cache List?  


    Certificate Cache List at “Monitor > UTM Statstics > SSL inspection > Certificate Cache List”
