First, you need to configure your computer's hosts file to map the subdomains to the localhost (127.0.0.1). You can find the hosts file in different locations depending on your operating system.
Windows: C:\Windows\System32\drivers\etc\hosts
Linux/Mac: /etc/hosts
Add entries for each subdomain:
127.0.0.1 <techname>.pb.local
For example 127.0.0.1 lviv.pb.local
