With the new MacOs Big Sur update, its looking like port 55555 is blocked by the operating system. A query to the list of processes that are using that ports return nothing lsof -nP -i4TCP:55555 | grep LISTEN which is expected. However when attempting to start a server on that port an error is received:
The issue here is we have a product with 15K+ docker downloads that depend on this port and up until now it seems a bit mysterious why this port is blocked by the OS only on BigSur; non of its predecessor OSs had this port blocked.
Anyone is facing this issue or has an answer to why is this the case? Thanks!
nc -l 55555
