Anyone else not able to get onto the DPT moderator website? Been trying for a week or 2 and doesn’t allow me on?

Many thanks Ben

Works ok for me too.

Could it be 'adults only' that mobile telephones etc. like imposing on us?

Or it could be areas of the network that is temporarily down?

On my Mac I get the following and have done for a few weeks.

Weird. It's valid here?:

Are you all seeing a certificate error? Are you all using a Mac? Are you all using 'iCloud Private Relay'?

Would those who can't access, please give us a clue why you can't!

Certificate error behind the first page. Win 11.

Doesn't seem to be iCloud Private Relay causing the issue for me.
See David's post above too, he's on W11.

I can't access the website via Firefox, similar message to Safari.
I can access the website via Parallels, W11, Edge.

Windows users, would you be willing to send me your DNS settings?

**ONLY SEND TO ME IN DIRECT MESSAGE**

Open 'Windows' CMD...



Then type:
ipconfig /all

Copy/Paste = CTRL+C, CTRL+V

I think there is something amiss with the DNS records...

I've managed to get a revoked certificate error using my phone via Vodafone:



Is this the error the rest of you got?

I’m a bit flummoxed because, as far as I can see, there is nothing to stop a certificate, still in date, from not working!

I get this certificate on iPhone. Like you say, it is an in date valid certificate.

The error as reported in post #5 is that the certificate for the DPT site has been revoked.

A SSL/TLS (technically x.509) certificate can be revoked by either the CA (root Certificate Authority) or intermediate, this is normally achieved through the issuing of a CRL (Certificate Revocation List); CRLs are distrubuted downstream from - but this does not guarantee that all intermediate CAs, proxies etc get them.

It's not unknown for CRLs to contain errors... and are quite a clunky method of checking the status of a certificate. Most moders systems/orgs will now use OSCP (I'll avoid sending folks to sleep with an explanation of how that works )

I have no knowledge on this area, however from a customer point of view, the DPT website appears very old and could do with an update.
