I’m new to the community, so - hello guys
First off, Let’s Encrypt is excellent. A-grade protection for a too-good-to-be-true price tag, which is free
Now, I have a slight issue: I run blogs, and usually submit my URLs to bookmarking sites like http://www.bizsugar.com. The thing is, since I migrate my site to HTTPS (with SSL certificate from Let’s Encrypt) the site gives error 502 (bad gateway). BizSugar.com uses Cloudflare, and I notice that submitting to other sites using Cloudflare give the same error message.
Another blog of mine is using Comodo SSL, and it’s working fine with the site - so I came to a (noob) conclusion-slash-question: Is this due to my Let’s Encrypt SSL misconfiguration or compatibility issues?
Please kindly advise. For testing purpose, one of my sites that use Let’s Encrypt is https://www.noobpreneur.com. I use SSLlabs.com SSL checker, and all is fine. I’m quite confused.
