TURN over TCP only not working

[JonathanYuzu]

Hello,

I have Coturn up and running for pixelstreaming hosted on AWS.
From what I understand, if there are no UPD ports available, it should work over TCP.
But when I block all UDP ports with a firewall on my PC it does not work.

When using TrickleIce I see a UDP replay but no TCP

I have added the tcp-proxy-port option (set to 443) in the turn.conf file.

Is there something else that needs to be done or is it not working?

The goal is for it to work even on networks with strict policies like no UDP and only port 80 and 443 open on TCP.

Thanks in advance for any help that can be given to achieve this.
