Live Stream with object storage

I have Peertube 5.01 working very well with object storage (s3). But now livestreams do not work. What am I missing? is there a new setting in the YAML file?
I am sure I have missed something. Can anyone give me a direction to look?

Thanks!

For live streaming you need port 1935 opened. Most probably you are using a CDN like Cloudflare where the 1935 port is not opened, so your connection will get always refused.
