Secong site of multisite is not working

HI ,

I installed multisites using virtual hosts. The parent site (https://multisite1.localhost/) is working fine. But when I try to open second site i.e https://multisite1.localhost/multisite2, it says “The requested URL /multisite2 was not found on this server.”. I know it’s because of virtual host but don’t know how to fix. Please help
