python – FFMPEG Failed to Connect to UDP Stream in Kubernetes Pod

I have a pod inside my kubernetes (openshift) cluster. The pod tries to connect to a remote UDP video livestream to read frames to be processed.
I find that the first 2-4 attempts that the programs makes to connect to the stream fail (timeout) but after around 4 attempts the stream can be connected.

It is even more strange to me because there are multiple stream IPs:ports. So there are times when connecting to a IP/Port fails a couple of times at the beginning but afterwards the program has no issue connecting to a various number of stream sources.

My question is does anyone know why this may be happening and if not, I’d appreciate any suggestions as to how to debug the situation and understand better ffmpeg’s behaviour.
