This is great info. I haven’t seen CORS issue specifically, but I’ll dig more on this. If I find anything I’ll post it here.
After seeing the scripts looks like is related to Cloudflare, are you using Cloudflare? https://boards.neocron.org/cdn-cgi/apps/head/QNWX_8GN-3K7wUr6Qa73LdoD3JI.js. We are not using that so probably we haven’t seen this specific issue.
