Freepbx 12 self signed certificate issue

I have installed FreePBX-6.12.65-15-i386-Full-1409755441.iso distro and generated new self signed certificate in “Admin > Certificate Management” page as described on the wiki page. I can see generated files under /etc/asterisk/keys folder. Certificate Management page says

A Certificate Authority is already present on this system. Deleting/Generating/Uploading will invalidate all of your current certificates!

However cannot enable webrtc on User Management page. It says

You have no certificates setup in Certificate Manager

Already done “amportal restart”. What would you advise next?

Looks like you only did half the work. You generate a CA then you need to generate certificates. Looks like you only generated a CA

Ah yes. Sorry for not paying more attention.
