Hey guys, I’m still working on it. But I think I’m getting close.
My setup is:
Nginx 1.10.3
Digital Ocean Ubuntu 16.04.2 x64
Mautic 2.8.2 installed on a subdomain
I was using cloudflare for DNS, and installed their certificate with ‘flexible ssl’ option for https.
So the problem seems to be stated here:
On this article, they instruct to create a site rule, forcing https always on this domain., I tried that and didn’t fix the problem.
The only solution, for now was to turn off all the Cloudflare SSL/TLS Https setup and get back to plain HTTP on my server.
But maybe, Cloudflare https solution is not the way to go. Letsencrypt should give less problems.
