Hey, I’ve been getting an intermittent 525 error on https://eola.co
It seemed to be happening to roughly 1 in every 50 requests. I think it’s managed to fix itself now (which I think is actually more concerning). The only thing that I touched when trying to fix it was trying to downgrade the SSL type from Full (non-strict) to Flexible. I immediately changed it back. I hope that wasn’t the “fix”.
It was never in strict mode, and regardless, the origin web server does have a cloudflare origin certificate installed.
I didn’t see anything on Cloudflare’s status reporting that seemed to be related to an SSL problem, and Heroku wasn’t reporting anything either. I haven’t touched the SSL setup for about a month. We use Argo.
Any guidance on what might have happened or how to prevent this in future would be ideal.
