I moved to a new shared host with DirectAdmin and Let’s Encrypt, once I changed the CloudFlare SSL encryption mode to Full (Strict), I am getting a error 526.
I have used “Paused CloudFlare on site” and tried reloading the site with various computers via different ISP. I confirmed the site was working and the certificate is issued by R3 and it is valid.
When I resume CloudFlare and enabled the CloudFlare SSL mode back to Full (Strict), error 526 is coming back.
Currently the site is set to use Full only, and I confirmed a CloudFlare cert was issued and I am curious to get to the bottom of this.
As far as I can tell, the problem seems to be with CloudFlare because turning it off and everything is working. Any idea?
