- You need to use FQDN (Fully Qualified Domain Name) format:
https://coolify.io - You can give multiple domains, separated by comma:
https://coolify.io,https://www.coolify.io - You can also add a port to the domain, so the proxy will know which port you would like to map to the domain:
https://coolify.io:8080,http://api.coolify.io:3000
Wildcard Domain
You can set a wildcard domain (example: http://example.com) to your server, so you can easily assign generated domains to all the resources connected to this server. More details
