[🐛 Bug]: Node not registering on Hub in the same machine for Client in their office N/W

[adas05]

What happened?

Hi! We have a client setup where HUB and NODE are running in the same machine. For few users this set up is working fine, but for few others the NODE keeps sending the "sending registration event..." and the HUB do not registers.

We have taken these steps to identify the issue:

1. Checking if the following ports are opened or not for Ports: 4442, 4443, 4444, 5555
   using this command netstat -ano | find "PORT"
   For PORT 4442 we found that we get the status as SYN_SENT, so this made us check for all the above PORTS to be opened in these IP ranges for the clients.
2. The client connects to their office n/w and then they start the HUB and NODE.
3. They have their firewall setup using Gamma and not Windows default firewall.
4. On checking with the infra team they have informed us that the ports are opened for all IPs generated for the clients.

Note: we have tested the same HUB and NODE config with different PORTs range from 7777, 7778, 7779 (HUB related) and 8888 for NODE - this also did not work (which is understandable)
We have asked the infra team to re-check the IP ranges in which the above PORTS are opened and waiting for their response.

Could anyone pls suggest if we are missing some other config related changes?

Thanks

Are the affected machines running with VPN connections? It may be insufficient to specify localhost; you may need to use a strategy like this to identify the proper internal address:

https://github.com/sbabcoc/Selenium-Foundation/blob/master/src%2Fmain%2Fjava%2Fcom%2Fnordstrom%2Fautomation%2Fselenium%2Futility%2FNetIdentity.java

To use this class:

new NetIdentity().getHostAddress();
