Hello, I discovered this morning that Cloudflare now enforce browser challenge on https://www.ispconfig.org. Well, but it also challenge non-browser requests, such as curl, wget ... even if User-Agent is not immitating a browser and even if "text/html" is not specified in "Accept" request header. As a result, automated download and/or even version checks, such as those done in ispconfig_update.sh, are no longer working. So please fix it, eather implementing some specific exclusion based on URL, User-Agent, and/or Accept request headers in Cloudflare, or change URL to another subdomain or whatever which is not affected by any browser challenge.
