Site issue confirmation

I'm seeing some weird timeout errors, but can't find the reason yet.
Other editors are seeing the same problem ?

I've fixed it, it was due to old redirects (like after editing a game you get to the game page) to http instead of https.
It was auto-corrected on the fly by both the server and Cloudflare (used for certificates and CDN), but one of these two has started behaving differently.
