Ubuntu cant connect to port 8433, port is open, Kurento Media Server
Kevin D
stalled Kurento media server using the installation guide found here : http://builds.kurento.org/dev/master/latest/docs/installation_guide.html
I opened the ports in UFW
sudo ufw status
Status: active
To Action From
-- ------ ----
22/tcp ALLOW Anywhere
8433 ALLOW Anywhere
8443 ALLOW Anywhere
8888 ALLOW Anywhere
I started the server using sudo service kurento-media-server-6.0 start . I got no response, but the log file seems to suggest it started.
I checked netstat -l to see if it was listening to the port.
netstat -l

it appears to be listening,
Next i checked ss -lnp | grep 8433 got this response
ss -lnp | grep 8433
tcp LISTEN 0 0 :::8433 :::* users:(("kurento-media-s",pid=14442,fd=8))
Seems to be listening ...
So first I checked using this website to see if the port was openhttps://www.yougetsignal.com/tools/open-ports/
It claims it is closed.
Next I checked by using the wget command targeting the port on local host to see if I could get a connection.
wget localhost:8433
--2018-03-06 20:00:07-- http://localhost:8433/
Resolving localhost (localhost)... ::1, 127.0.0.1
Connecting to localhost (localhost)|::1|:8433...
Gets stuck while connecting. it never connects it just sits.
What am I missing ? I cant even start the kurento tutorials because I cant connect to KMS at all ...
Any advice would be apreciated, I dont know where to go from here. .. .

I will try to contact them and see what happens.
Thanks for the advice.

It appears UFW is in fact incompatible with Kurento for some reason ...
