I am facing a very strange problem with the system...
The system has been running for more than 1.5 months and now I am unable to access the HTTP (Port 5172) and neither is it responding to PING.
But strangely the system is responding to SSH on port 22 and I am able to login through SSH.
I also rebooted the system twice but still the problem is there.
Anyone else faced this issue?
Thanks for the clarification about connections. Actually I used iptables to filter the ports. To remove the filter you can use "sudo iptables -F". Anyway this should not be the reason why the system is unreacheable. In case there Is a problem with hydrosys4, normally you should get a "bag gateway" message in the browser which is sent by nginx that is acting as reverse proxy. Anyway I suggest to see if the hydrosys4 starts manually using shh so you can see the logs. Login with SSH, type "sudo killall python3", this command should not provide answer, if it says no python process, then there is an issue with the SW. Then go to the folder "cd env/autonom" then type "sudo python3 bentornado.py" you should see the program starting. If there is an issue we should be able to see
