[🐛 Bug]: Unable to use same port across multiple nodes in selenium grid 4

[remyanekkuth]

What happened?

The way grid 3 set up was environment integ and pre-production will listen to port 5555 . Integ will listen to development server hub and pre-production in prepoduction server hub. sandbox and user acceptance will listen to 4444

In grid 4 same configuration we did for port 5955 4944 respectively. Integ is working fine. But when try to run the command with --port 5950 getting error " address in use" how can we use same port across multiple nodes.

command we run is

JAVA -jar "jar " node --hub http:selenium:5955/grid/register --port 5900 --host "computer name "

How can we reproduce the issue?

Two nodes with same port in different environment with different server.
Add first node and validate 
JAVA -jar "jar " node --hub http:selenium:5955/grid/register --port 5900 --host "computer name "
go to the second server, configure same port for diff envt. and run again
will get exception at point --port

Relevant log output

value is not acceptable for --port .

A few things, http:selenium:5955/grid/register is not a valid URL to register, and we also need the full commands and logs for each command. We cannot triage this until more information is provided.

@diemol I set up this port and hub was working fine. I was able to resolve the issue by mentioning—publish-events and —subscriber-events .
