Question

PORT 8888 doesn't respod

Posted February 14, 2021 504 views

Hi guys,

I don’t know much about back-end, and other person built the system.

But all the images of my sites that are at port:8888 are not appearing anymore. I don’t see anything in my log error, the port is simply not responding.

The only tip I have is that I see nginx and redis at the system, and a phyton is what I have at port 8888.

(My system is linux 14)

Any tip?

Thanks.

If no records in nginx log (access.log & error.log), two things to check first firewall and firewall! If logs showing hits with errors, then you start from that point.

Check your DO firewall settings. An Introduction To DigitalOcean Cloud Firewalls

Second is your linux firewall, if enabled.

You can test using online tool for ports i.e. Is Port Open

Hello, @revistagarupa

You can check if there is any service listening on this port using ‘netstat’

  • netstat -plunta | grep 8888

If there is no configured service on this port but the port is used as a socket you can also do a curl or telnet on the port and see if a connection can be established.

telnet DropletIP port

curl DropletIP:1234

If the connection can not be established then the issue is most likely related to your Firewall configuration.

Hope that this helps!
Regards,
Alex
