Troubleshooting • Ethernet Connection failing after prolonged accessing

Ok here's the summary of the issue and what I have tried:

currently my set up is as follows

computer1 ----> computer 2 -----> Serial Device
eth serial

I am currently able to send commands individually from computer 1 to computer 2 to serial device automatically. This is done by hosting a script on computer 2 that is constantly on and listening for commands to translate. I have a script on computer 1 called "send_command.py" that sends ONE of the commands I want to send. When I do this it works perfect. I also tested having another script that runs "send_command.py" over a period of 30 minutes without any issues.

However when the set up is changed to be

computer1 ----> Raspberry Pi -----> Serial Device
eth serial

I can still do the single "send_command.py" however the longevity test (running the send_command.py script multiple times) fails with a "A connection attempt failed because the connected party did not properly respond after a period of time or establish connection failed because connected host failed to respond." I can confirm with confidence that this issue is taking place between the ethernet communication of the computer1 and raspberryPi 5. Weird thing is though that this issue does not happen when between computer 1 and 2.

Not sure how to move forward with this.
