Failed to send a ping request or response. Using external API

I am using the external API on my website, hosting my own Jitsi Server.

I keep on getting these errors:

Logger.js:154 2020-03-25T12:24:02.885Z [JitsiConference.js] <e.sendMessage>: Failed to send a ping request or response.

What does this mean?

Hi there,
I have the same runtime error popping up.
Check if you can connect more than 2 people to the video conference.
The two issues might be connected?

No, I can’t indeed…

So I started from scratch. Connecting with externalAPI with meet.jit.si
Console show continuously:
