Can't open custom port (8079, 8088, 8082 etc.)
Can't open port for my docker container. I started docker by:
docker run -p 8079:8080 -p 50000:50000 -d jenkins
After this i added rule for ufw:
ufw status
Status: active

Also, I tried:
iptables -A INPUT -p tcp --dport 8079 -j ACCEPT
but with no success.
The netstat response is:
netstat -plutn

How can I fix this problem?
Well, it seems port 50000 is blocked by ufw, since port 8079 is allowed by the fourth ufw rule in your list. I would try a
sudo ufw allow 50000.Thank you, but this isn't the trick... I tried and again with no success/
Hey! I wasn't notified of your reply, sorry :(
You don't seem to have a TCP port problem by your last output.
The
403 Forbiddenis generated by your app! It seems a directory permission problem!
