Can not log in control panel

I purchased a VPS in linode.com today with CentOS Stream 9 (Linode currently only provides CentOS Stream 9).
After installing CWP7 and adding a domain, I found that logging into this domain's control panel failed (https://*****:2083), but I could log in to FTP with the same user and password.

Also, in the WebServer Settings ->SSL Certificate, I found that the Let's Encrypt SSL Certificate was not generated for the domain.
Based on previous experience, Let's Encrypt certificates should be automatically generated.

How can I fix these problems?

CentOS Stream is a beta-quality OS, not really suitable for use as a server foundation. Please use AlmaLinux (preferred) or Rocky Linux 9 as the basis for your new server.

Their site shows they offer AlmaLinux 8 and 9, as well as custom images.

If you don't need PHP support under 7.4, I would go with AlmaLinux 9.
