Parallel Pool No data errors

I am failing to start a parallel pool (which was starting just fine 1 week ago... the only change is that I unplugged the ethernet cable).

This is the error I am receiving

Underlying error: failed to bind to endpoint

Cause: resolve: the requested name is valid, but no data of the requested type was found (system:11004)

Is the pool running locally? Or are you running it on an HPC cluster (e.g., MJS, Slurm, etc.)?

[Deepika Gupta]

locally, I think

Glad you mentioned that you unplugged the Ethernet cable, that helped me track this down a bit (I think).

It appears as though this might have been fixed in R2021a and backported to R2020b (not sure which update). Which version are you running?

It's 2023a

and for some reason, plugging the ethernet cable back solved the issue. The ethernet cable is not connected to anything else, neither the internet nor another computer. It's just plugged into the wall.

I was recently seeing some oddities in link state on a Mac, times where it thought a link interface was connected even though I was fairly sure the other end was down. I was working with some pretty old external hardware at the time (2005-ish).

Historically, on PC plugging in one end of an Ethernet cable to a half duplex Ethernet card (and I do mean card!) could trigger a link reset that could lead to state glitches. By the time of auto-negotiation with 100 megabits, this had been completely resolved for nearly all cards except some of the very very cheap ones.

This was, of course, difficult to figure out.

I had the same problem and parallel didn't work after installation. Save me
