Why I can't navigate to crm portal

I installed frappe crm.

But when I click on CRM Portal Page give me not found like this image!!

@NCP
can you help ?

Hi ,

I may help to say the operating environment and the steps taken to install the app.

I installed this app using commands:
bench get-app builder
bench install-app builder

Try the Local setup instructions found here: GitHub - frappe/crm: Fully featured, open source CRM

It appears that the install-app command didn’t have a --site so not sure why it worked at all.

Builder is a Frappe Framework app for building websites.
If you want to install the CRM app:

$ bench get-app crm
$ bench new-site sitename.localhost --install-app crm
$ bench browse sitename.localhost --user Administrator

Okay but also when I install builder not working give me not found when I click on open builder in my desk!!!
