These issues could happen with any service such as Bluetooth, PKI, Fido or Fingerprint.
After you install a new browser and then try to enroll or test authenticator, an error message Service is not available is displayed.
The root cause for this issue is, device service keeps the certificates for itself during installation. So if the browser is installed after installing the device service, the browser will not have the required certificates.
To fix the issue, open a new browser window and access one of following URLs. Depending on the method used, apply the appropriate certificate.
