Open port on buisiness firewall


New Member
Hi guys,

I have an issue with OBS when I try to launch a stream on youtube studio. I had the message " The connection was blocked. Check your firewall / anti-virus settings to make sure OBS is allowed full internet access "

The issue come from the buisiness firewall, when I try to stream from another connection (like the hotspot of my smartphone) it work perfectly.

When I open entierely the firewall, it work, but I can't find the specific port to permit to stream.

Can someone help me please ?

Thank you in advance,
