Unable to join meeting with link

Have just finished setting up my local jitsi box…but whenever I create a meeting it seems everyone I invite gets to their own meetin as it it states you are the only one in the meeting . Please assist.

Check your js console logs in the browser, do you see any errors?

this is the only warning we see
“Strict-Transport-Security: The connection to the site is untrustworthy, so the specified header was ignored.”
