I installed Pi Hole with OpenVPN on DigitalOcean following this guide.
https://www.digitalocean.com/community/tutorials/how-to-block-advertisements-at-the-dns-level-using-pi-hole-and-openvpn-on-ubuntu-16-04
I did not do anything that’s not in that guide include setting these iptable rules (
https://pi-hole.net/2018/02/02/why-some-pages-load-slow-when-using-pi-hole-and-how-to-fix-it/).
This mostly works fine, except so far I’ve been able to find a couple of websites that do not work. I get the error below for them (both websites are https only).
Expected Behaviour:
Visit
https://itchy.nl, it should load the site (https).
Actual Behaviour:
This site can’t be reached
The webpage at https://itchy.nl/ might be temporarily down or it may have moved permanently to a new web address.
ERR_SPDY_PROTOCOL_ERROR
At first I thought this was a problem with Pihole so I disabled it. Sadly, the problem was still not resolved. I've tried multiple clients (mac, android) and browsers, and the site just fails to load (pretty much instantly).
I tried to set up some logs to see if the connection to the site is made on my VPN, but I could not find a way to set those logs (log-append wasn't transparent enough).
