Hi,
I’m getting 502 Bad Gateway error when turning on SSL for a Wordpress website hosted on Digital Ocean Cent OS 7 vps. Site works fine without SSL through Cloudflare, issue arises when Flexible SSL is turned on, it results in 502 Bad Gateway. It worked fine for a few months without any issues, problem seems to be occurring since yesterday when i had to update the DNS.
Funny thing is Another Wordpress website on the same server works perfectly fine with Cloudflare SSL without any sort of issues.
How do i diagnose this problem ? No errors are being logged by Apache on my server. Pls help !
