BigBlueButton 2-3-dev html5client showing "404 not found" nginx error

Question

Lately I have installed bbb 2.3 on my Ubuntu 18.04 VPN server. After a few road-bumps it installed and bbb-conf --status shows no error/warning.

Calling API is also returning SUCCESS response, but the html5client, when running in browser is showing 404 not found error. API Response HTML5CLIENT

I have tried troubleshooting from the bbb docs itself but nothing changed. What could be the possible reason?

check this file to see if BigBlueButtonURL is correct and https:

/var/lib/tomcat8/webapps/demo/bbb_api_conf.jsp

(tomcat7 in the case of tomcat8 doesn't exist)
