To remove domain and set again IP for access:
opencli config update force_domain ""
opencli config update ssl no
Then next opencli admin on
will start it.
Its better to investigate why the domain Is not being set. make sure you add it as hostname and point to ipv4: https://openpanel.com/docs/admin/settings/general/#set-domain-for-openpanel
For debugging, you can set it from terminal with opencli ssl-hostname fqdn_here
and it will show any problems
