What prevents you from viewing the certificate? Can you click on the<br>
site information icon to the left of the browser Location(?) bar when<br>
the error is displayed? If not, perhaps you can use FireFox built-in<br>
"Web Developer Tools" (Ctrl-Shift-I on my machine) to get to the<br>
certificate? I am not a browser expert, but there is usually a way to<br>
see the certificate if the browser received it.<br>
<br>
If nothing works, can you try reproducing using curl or wget instead of<br>
a browser?<br>
<br>
<br>

<br>
That would give you the third certificate to compare.<br>
