Adding a Security Exception

When FireFox encounters a self-signed cert, it won't load the page. The way to make it work is to add a Security Exception for that particular website.

The Add Security Exception dialog will be displayed. You need to enter the host and port used to access the web page you want. For example, if you want to access the following report:


you would enter https://dnvista:82

Once you've entered the URL, press Get Certificate. The cause of the problem (unrecognized authority) will be displayed.

Check the box near the bottom ("Permanently store this exception") and press "Confirm Security Exception".

From this point on, FireFox won't show SSL-related errors when visiting this URL.

Mismatched Address

If your server is accessible via different names or additional IP addresses (perhaps via an external and internal IP address) then the URL won't match the internal server name and the browser will give a Mismatched Address error. This is the same error that occurs if you take the SSL certificate from one server and put it on a different server

One fix would be to go back and add another Security Exception for additional URL. Optionally, you could also add an entry to your hosts file that maps the server's name to the IP address that you are using to access the server. That will enable the URL to match the certificate.

With [major competitor's] ping reporting feature I get an email alert for *every* ping failure. Since it's normal to occasionally fail ping (busy network etc) my Inbox was constantly flooded with nuisance alerts. The way you have it implemented I only get the email alert if there is a real problem that needs my attention.
