Hey Yannick! Just following up here in case others are interested in our testing results. I completed a full round of testing under a Cloudflare proxy and while I ran into some initial issues getting SSL working between CF and my test environment; I was able to get it running behind that proxy. I tested basic ticket functionality, KB usage, Live Chat interaction and updates, etc and found no obvious issues. So, at this point I can't say that I see any issues that should prevent you from testing Cloudflare against your environment specifically. If you do run into any questions along the way please don't hesitate to ping us as we'd be happy to take a look. Have a good one!
