Hi, I've opened a few ports which I need. When checking, the seem open: Code: 17178/tcp ALLOW IN Anywhere 17179/tcp ALLOW IN Anywhere 17180/tcp ALLOW IN Anywhere 17181/tcp ALLOW IN Anywhere 17178/udp ALLOW IN Anywhere 17179/udp ALLOW IN Anywhere 17180/udp ALLOW IN Anywhere 17181/udp ALLOW IN Anywhere as it does not work, i've checked with an port checker online, and also with telnet, the ports seems to be closed. Where should I look to solve this? Thanks very much.
Perhaps they are blocked in a network router or firewall. Check your own if you have one, and you could contact the company which hosts your server next.
Called with Strato today. They say they don't block any ports on self managed VPS. When checked in terminal ufw, says the ports are allowed from anywhere. nmap does not show the needed ports at all. The site https://www.yougetsignal.com/tools/open-ports/ shows the ports closed. What can I do next? Thanks for any help.

That clearly shows the ports are allowed in iptables, so the ufw configuration is working. It also shows you have nothing listening on those ports, so any test connections or traffic must fail at this time; your issue likely isn't a firewall blocking the traffic. Go ahead and start whatever service(s) you have which should be running there and test again.
Thanks Jesse. It's a java server started with this command Code: nohup /home/user/jdk-11.0.12+7/bin/java -jar /home/user/app/jRDC.jar > nohup.out & which looks like it started ok Worked great on the Raspbery, it looks like everything what runned ok there, I have trouble with on VPS (except the email due to port 25 on the raspberry) Did not expect for this that it has actually to listen to check if the port is open. Thanks I will check.
Yes indeed it works now. Strange, before I could use the whole string as in the previous post and it would start. Now I have to cd to the java bin folder and then use nohup java -jar etcetera. Else it says can't execute binary. At least a step further into the puzzle.
