I am using Chrome and Edge to visit a web site that requires client certificate (mTLS). For the first time, both Chrome and Edge pops up a panel that asks me to select a certificate. There was only one to choose, the sole one in my Personal store (Windows 10). I could visit the web site.

After I rebooted my computer, when I tried to do the same, I received a 400 error response with the message "No required SSL certificate was sent". How do I include the certificate in the request again?

Restart Chrome, so that the certificate popup is shown again.

To do that, type in the following address into a new chrome tab/window:

chrome://restart

This closes and reopens the windows with all the tabs you had (as it worked for me, no warranty) The restart procedure is also described in How to Restart Google Chrome

If the certificate has disappeared from the Personal store, it should still exist somewhere on your computer from when you received it.

Try to import again the certificate to the Personal store:

  • Open Chrome
  • Click the three-points menu at the top right corner
  • Select Settings > Privacy and security > Manage certificates
  • In the Certificates dialog, click Import...
  • Click Next, browse to the certificate file
  • Continue as indicated to import the certificate.
