I just changed default domain to localhost and ssl type to upstream. I just want to install odk using local server with no public ip and access to through internet using port-forwarding but the server hosting odk-central has only private ip. it just works I sharing this in case some people which is wanted like my scenario might benefit this. I don't know if this is already knowable by everyone I did not see on docs and community questions thanks.
DOMAIN=localhost
SSL_TYPE=upstream
