The error code is net::ERR_CERT_COMMON_NAME_INVALID. If I click the error code, it shows two long certificates, but I never know how sensitive they are, so I decided not to paste them here.
Checking Pi-Hole’s log, these seem the addresses it blocked:
Does anyone have any idea what happened? I know I can unblock the above mentioned domains, but the seem to be the kind of domains one would like blocked…
(I also tried deleting all cookies, but no effect.)
The server certificates presented to your browser by the server can be shared, as everyone connecting to the server can see them, there is nothing to hide.
To me, it seems the block and the error are not related, though I don’t understand Dutch
I don’t know what Pi Hole does when blocking a domain, but I’d think it returns an invalid IP not pointing to any server (like AdGuard Home does).
The security error though indicates that openhab.org is resolved to someone else than openhab.org, and that someone else can’t present a valid certificate for openhab.org.
Can you please share the certificates?
And please share what nslookup openhab.org returns.
Okay great. I would suspect there was an DNS issue, though it was not that there were the mentioned addresses blocked, but openhab.org seems to have been resolved wrong.
I also have pihole installed, but tried it from a machine at work. It’s the same IP as a resolved by 1.1.1.1 (for www. openhab. org - just openhab. org isn’t beeing resolved):

I also get the wrong wildcard certifcate from above.
PS: I had to add spaces into the hostnames, to post it.
Sorry, the issue is because the certificate from Netlify is not issued for openhab.org; typically, we proxy it through Cloudflare, so that Cloudflare provides a valid TLS certificate; temporarily, our nameserver is now not the Cloudflare one, so that the proxying does not work. I hope that I can fix this by this afternoon again. Sorry for the inconvenience!
Even better - I was able to generate a new LetsEncrypt certificate on Netlify, so that it is now serving a valid one, even without Cloudflare! So www.openhab.org should now appear correctly again.

Sorry that I try to post here. But I try to create a new topic and just get an error message. What can I do?

Hi @habnewbie, this is weird and should not happen. I see that you already registered a month ago, so the message is definitely wrong that it is your first day. I also checked that you have already trust level “basic user”, which means that you should have all standard rights.
My only explanation is that this is a bug in the forum software - I have just done an update to the latest version in the hope that this fixes the issue. Could you try again and let me know?
