For some reason when I type in https://www.gro.gov.uk which I have used previously on this computer it comes up with as below, yet when I do this on a different browser it is okay, could it be I am using adblock or ublock origin and if so what do I need to do? many thanks jules

Hi jules_herdy, here's the background:

The original site you want to visit isn't sending an intermediate certificate, and therefore its certificate can't be verified.

If you visit a different site that uses the same intermediate certificate, Firefox will cache it for future use. (You don't need to do anything more on that site.)

Then after that you can visit the original site you wanted to visit and Firefox will use the cached certificate to bridge the gap.

Does it work?

ok thanks, so basically it's a configuration error of the webserver (an incomplete certificate chain) that makes it depend on chance* whether this will work in a browser or not: https://www.ssllabs.com/ssltest/analyze.html?d=www.gro.gov.uk&hideResults=on

in order to fix this on your end, visit this site once - afterwards the misconfigured UK government website should start to load without errors as well.


* it's not really chance, but depends if your browser has come across any other website that has implemented the same intermediate certificate correctly and if the browser therefore has stored it in its certificate store already.
