Pihole Not loading Letsencrypt Certificate

[LDV9000]

Hello,

i don’t know where to start.

Since version 6, PiHole is no longer an application that uses a regular web server. Therefore, the letsencrypt certificate does not work out of the box. However, you can use your own certificate in PiHole even with version 6. For more information, please refer to the PiHole documentation.

Hi,

I managed to get it to work on 80/443 ports and with the letsencrypt certificates.

thanks,

Did you followed the PiHole documentation or used another way?

[LDV9000]

I dint use the link provided that points to how prevents the browser warning but uses a self sign certificate.

I’m using let’s encrypt certificates, so I went another way.

[Joulinar]

Well, very last point on the PiHole docs is describing how to use own certificates. Not necessarily self signed once.

[LDV9000]

Yes, you correct. and i tried that but for whatever reason when i tried that i run into some errors and problems that i couldn’t even understand, but that documentation pointed me to google search’s and i eventually found another way to do it .

I’m using the default files locations and the normal ports 80/443

to renew the certificates i use the dietpi-lestencrypt

then just copy the certificates from letsencrypt to the pihole.
