  • Thanks. That seems to be a similar, but slightly different error. I think the below may apply though.

    I believe I’ve tracked down more of my issue, but fixing it is going to be a hassle:

    When cloudflare proxying is enabled, there are 3 DNS records involved; A record with cloudflares ipv4, AAAA record with cloudflares IPV6, and the key to this puzzle: an HTTPS record with cloudflares ech/https config.

    With pihole I can set DNS records for A/AAAA, but I have no way of blocking/setting the HTTPS record so it gets through from cloudflare.

    The LAN A/AAAA records don’t match the HTTPS record from cloudflare, so browsers freak out.

    Once I disabled cloudflares proxying, I no longer get HTTPS records returned and all works as intended.

    I’ll either have to keep cloudflare proxying disabled, or switch pihole out for a more comprehensive DNS solution so I can set/block HTTPS records :(

    Thank you @bobslaede@feddit.dk for pointing me in the right direction.


  • That unfortunately did not work. I am only getting the ipv4 address now, but I still get the same ECH error in chrome 1/5 tries.

    Firefox now changed errors from ‘invalid certificate’ to ‘connection is insecure but this site has HSTS’ (true). Still wont show the cert or provide any further info. (forgot to grab a screenshot before the below ‘solution’)

    I’m really annoyed at this point and have just disabled cloudflare proxying for this service. That seems to have sorted it for all browsers. I may look further later, I may just say fuck it and leave it like this. Gotta walk away for a bit.
