Are there issues with having Flexible SSL option enabled in Cloudflare when the edge server does have a valid SSL (as per cPanel AutoSSL)? Or will there be issues trying to send http traffic from Cloudflare to edge when https is expected?
Or is it best to have it on Full?
Sometimes AutoSSL fails to auto-renew. To get it to work on our host, I had to turn off Cloudflare for a bit, then it ran successfully, as it was checking for some edge DNS TXT values or something.
So I thought I just leave things as Flexible in case AutoSSL failed.
Originally I thought Flexible mode would try https first, then fall back to http if there was an SSL error or no SSL found on the edge.
I’ve recently been having an issue with my setup, regardless of using Full or Flexible, or whether Edge had an SSL or not. It’s to do with intermittent down-times throughout the day preventing access to our website for 10-20 minutes at a time.
I reset Cloudflare so it could obtain the latest DNS from edge, but the DNS A name for www was still the same IP. Trying to work out if my host provider knows of any issue, but they keep blaming Cloudflare, and Cloudflare alerts me automatically to check with my host provider.
We are not using HSTS, and we use Cloudflare page rules to redirect to https://www
Just trying to determine what it could be. I don’t want to end up having to move away from Cloudflare, as it has nifty features and stats, and protection.
Not sure if my website caches well with Cloudflare as it consists of 1 .php file, which I use query strings to determine which page to display (thus which include file to dynamic process). My site is image gallery heavy (with many JPG files). I’m assuming Cloudflare cache’s those, but not sure if can cache dynamic pages?
I wonder if when Cloudflare refreshes it caches, could that be causing outages?
I did ask our host for any known issues with Cloudflare, but not much help.
Thanks all. Sorry to include a few inter-related things in this post.
