[SmartCrawl] Sitemap is not being generated


I’m having a problem with SmartCrawl on my customers website. I have automatic sitemap enabled but I get a 404 error when I visit the sitemap file. I also noticed, that the crawl doesn’t start. I get a success message that the crawl started, but nothing happens.

I checked the server logs but there’s nothing that would point to anything related to this.

I have a ubuntu server running nginx and php 7.3. The website routes via cloudflare.
