Installed with wrong domain and need to change, help!

During an install on Debain 9 I accidentally put in my hostname BigMama instead of the subdomain that I setup “videochat.example.com” . I uninstalled with sudo apt-get purge jigasi jitsi-meet jitsi-meet-web-config jitsi-meet-prosody jitsi-meet-turnserver jitsi-meet-web jicofo jitsi-videobridge2 porosody and reinstalled via instructions from Jitsi and the screen that pops up asking for the domain name never shows up. It seems to skip right by it and go to the certificate screen. I have been banging my head against the wall to try and get that screen to show up… even went as far as to sudo find / -iname *"jitsi"* and delete any filename that showed. Thanks in advance if anyone can help.
