hello
I have to do what for this problem

What’s the CMS version please and if it is 1.8 series is it docker or custom/manual installation?

Do you the same address in the URL in browser to access the CMS?
Since it’s localhost I assume the player and the CMS are on the same machine?

yes in the same machine and the same address in the url

I assume that’s 1.8 CMS with manual/custom installation (ie non docker)?

You have web in the CMS URL, which implies incorrect configuration (documentRoot and URL rewriting), please see http://xibo.org.uk/manual/en/install_environment.html

thank you
Or I can find this root document
