In https://go.dev/issue/52545 we saw failures in the cmd/go tests on Google Cloud VMs due to a combination of a small number of available NAT ports and port exhaustion from TIME_WAIT connections, but the failure mode there was different (timed-out git commands rather than "cannot assign requested address").
If the problem is the total number of open connections, rather than connections in the TIME_WAIT state, you could try setting `GODEBUG=cmdgonetlimit=4` or similar in your environment, although I don't think that will prevent the accumulation of idle connections. It would probably be helpful to figure out exactly how many connections you have open (and what state they're in) when the error occurs. (When I was investigating #52545 I wrote a little `ss` wrapper to monitor connection states; see https://github.com/bcmills/cmd/blob/main/watchnet/main.go.)
