Probably will need to fill out the support template so we have more information to go on for provide assistance.

Search for cloudflare in this forum. If Cloudflare acts as a proxy (the default in many setups), you must configure various settings on the Cloudflare side. Otherwise, access from non-browsers will be blocked by the Cloudflare WAF, Bot Protection etc.

Tips for increasing the likelihood of a response

  • Use the preformatted text formatting option in the editor for all log entries and configuration output.

  • If screenshots are useful, feel free to include them.

    • If possible, also include key error output in text form so it can be searched for.

  • Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
