Ecran figé lors de l'accès aux menu sur nouvelle installation

Bonjour à tous, je suis en cours de réorganisation de ma domotique. Pour cela je suis reparti sur une installation complète (Debian 10 sous proxmox).
Mon problème est que lorsque je clique sur la barre de menu jeedom, de manière très régulière, la page est très longue à se charger, il y a parfois le logo tournant au centre de la page, j’ai fait plusieurs installation mais toujours le même problème… Lorsque j’ouvre la console Chrome, j’ai plusieurs message comme celui ci qui apparaissent au bout d’un certain temps :

DevTools failed to load SourceMap: Could not load content for http://192.168.1.54/3rdparty/jquery.contextMenu/jquery.contextMenu.min.js.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE

Mes connaissances sont trop limités pour interpréter cela, quelqu’un peut t-il m’éclairer ?
