[Fiware-lab-help] I cannot access a port of my virtual machine (altough I successfully activated ping)

[joan]

dear Fiware Lab Help,
after some playing around and trying several times, I have now a virtual
machine, with a small binary running. This small binary running has been
tested on a local server, and it successfully admitted connections through
port 8888

I have now moved the binary to the virtual machine, and it has been running
for some weeks. It seems to be stable.

Now, I have tried setting rules to allow access through this port on my
virtual machine to have the same communication.

First added this rule both for my security group. I now believe this only
owrks for virtual machines on your servers, so I also added it as on the
public network (the 0.0.0.0/0).

Neither of them allow my local application to connect through TCP.
Testing it with https://www.yougetsignal.com/tools/open-ports/
does tell me my port is closed.

I also tried with port 80, and that web page also told me that the port is
closed.
However, I managed to enable the ping service. And I can access it through
ssh.
And I can ping google.com from the virtual machine.


My account is associated to this email and my public ip is 185.52.32.61
I also attach a screenshot of my security rules.

What am I doing wrong?
Thanks,
Joan
