Certification Error: Navigation Blocked – Windows Internet Explorer

When trying to access any site with https (any secure site) following error occurs in Internet Explorer or any other browser.

There is a problem with this website’s security Certificate. The security certificate presented by this website was not issue by a trusted certificate authority.


when viewing the details of the certificate, you can see that the Root CA is not trusted by your computer.


Also there might be some other errors like – you are unable to add a blog entry in Windows Live Writer. When trying to add an entry it gives the following error.

An error occurred while attempting to connect to your blog:
The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.
You must correct this error before proceeding. 



Run Windows Update!!!


  1. Find a computer where you don’t get the error. If don’t have another computer than download the Root CAs file here. (this file will not be updated)
  2. If you do have a computer where you don’t get the error then just type mmc in run and press enter
  3. After the MMC opens go to file menu and click on Add/Remove Snap-in…
  4. Click on the Add button, select Certificates and click on Add again.
  5. Select computer account, Next and then Finish
  6. Close the standalone snap-in window and click on ok on Add/Remove Snap-in window.
  7. Now navigate to Trusted Root Certification Authorities > Certificates
  8. Now click on Action > All Tasks > Export.
  9. Give the file a name and save it, once saved come back to your problematic computer again and follow step 2 to 7.
  10. Right Click on Certificates > All Tasks > Import
  11. Just find the file and click Next and you might have press yes a few hundred times :-|
  12. If you have Windows SDK and .Net framework installed you can use the certmgr.exe with the following command.
certmgr -add -all -c "Savedfile.p7b" -s -r localMachine Root


  1. I am having this problem too. Well at first my WLW would give me the error about the SSL/TLS secure channel. I messed with a few things and now I'm getting the error

    There was an error connecting to your blog. The underlying connection was closed. Unable to connect to the remote server. I tried your steps going into the console area and importing a certificate, but that didn't work either. I downloaded your Root CA file since I don't have another computer. Any other suggestions. I'm just beside myself that I can't use WLW and can't find any support that knows much. My emails is hulseys@msn.com if you can provide any help for me. THANKS!

  2. actually i just fiddled with it again and now it is back to the ssl/tls error

  3. Hi Jaime,

    What Operating system are you using?
    what happens when you try to import the root.p7b file?
