I just cleared my entire cache for pale moon and still invalid cert.
Check the fingerprint
The valid one I get starts
SHA-256 Fingerprint B2 F0 F0 0B 40 14 SHA-1 Fingerprint 2E C0 9F BF 04 A7
... how though? There is no cert from this browser. I've tried safemode and same issue so it's not an addon.
Click on the icon with the lock symbol (pic8.co) and then click "More Information"
On the resulting window, click "View Certificate" and you should find the fingerprint htere.
