Centreon 20.04 after logging in the screen does not end

Hola @cristianandres9,

Centreon 20.04 is no longer supported (more information here: https://docs.centreon.com/current/en/releases/lifecycle.html#maintenance-table-for-earlier-products) but I’ll try to help ^^ 
Was it a fresh install or an update/migration ?
Did you try with another browser or in private mode?

Hello @itoussies If we had a 19.04 version that was failing so it was decided to perform a clean installation where all the centreon 19.04 components were uninstalled, the cengine cenbroker centcore and mysql, it was validated that there would not be any component related to centreon and a new installation was carried out. which ended correctly, and I tried entering other browsers such as firefox and incognito mode and the problem persists and I noticed that when entering development mode in google chormen and put the tablet mode this if it shows something

Hello @cristianandres9,

Did you check your apache configuration file (/opt/rh/httpd24/root/etc/httpd/conf.d/10-centreon.conf)? You can find out what the configuration is supposed to look like here: https://docs.centreon.com/20.04/en/upgrade/upgrade-from-19-04.html#configure-apache-api-access

Hola @itoussies Revisa el archivo /opt/rh/httpd24/root/etc/httpd/conf.d/10-centreon.conf y se encuentra correctamente según la documentación que me muestras te comparto una copia:
