Issue with accesing with domain names

192.168.0.201 is my vps IP
and its static ip is 202.88.237.202 ,also its 80 port is forwarded
i need to configure DNS-based multitenancy mode

Install / Update config dns_multitenant on

and i created 3 sites in erp

bench new-site silerptest.palmtecamphibia.com
bench new-site silerptest1.palmtecamphibia.com
bench new-site silerptest2.palmtecamphibia.com

and i created A record for this subdomains , but now am not able to access the erp next with domain names

have you added these sites to /etc/hosts ?
bench --site “yoursitename” add-to-hosts

Check the common_site_config.json file if you have a “default_site” entry line. Should not be there.

already added the host names

You tried below ?

silerptest.palmtecamphibia.com:8000
silerptest1.palmtecamphibia.com:8000
silerptest2.palmtecamphibia.com:8000

now am able to access 3 site from locally , now i need to point the domain to access the same from externally @msalim79
