My users are getting sporadic 520 errors as soon as I turn on flexible SSL/TLS on my domain:
Here’s the requested files I’ve been told to supply, is there anyone who know’s what might be causing this? I’ve asked the server hosts and they’ve told me the CloudFlare IPs are whitelisted and there’s nothing more they can think of to do!
Any support and advice would be very warmly welcomed!

Sadly I can’t see how to attach the HAR files…
