I would suggest to try the following:
1. You can test to see if you are getting traffic from IP by setting the rule to 0.0.0.0/0, if you see this is working, then you can restrict the firewall to only the IP he wants to give access. 2. Firewall rules are defined at the network level and therefore make sure that you follow this document <https://cloud.google.com/vpc/docs/using-firewalls> while creating the firewall rules to allow incoming traffic on ports. In this document in step 11, choose " specified protocols and ports" and enter values. 3. Review if you have used a network tag or used apply to all, if using network tags, you should be adding the tag on the VM <https://cloud.google.com/vpc/docs/add-remove-network-tags> too. 4. Also verify that the traffic is not being blocked at OS level. You need to make sure there is no firewall running inside the VM blocking those connections. 5. Check to see if the port is open or closed or filtered <https://nmap.org/book/man-port-scanning-basics.html>using nmap <https://en.wikipedia.org/wiki/Nmap> to view open ports inside the instance. 6. You also need to verify if the application running on your server is listening to specific port. To check this, try with this command. sudo netstat -ntlp | grep LISTEN In the output, if you don't see the application beside port number, then check if your VM is rightly configured to ports for your application.
