Fix Captive Portal Redirect from ".com" to ".net" -- 3

I need an experienced Linux/PHP/Apache network engineer to troubleshoot and fix a captive portal running on Ubuntu/Linux. Issue: - My captive portal was originally configured with hotspot.xxxx.com. - I have migrated to hotspot.inetwall.net because the ".com" domain has expired...
