socket hung up when building for iOS

Hi there
I’ve built for android successfully, but when building for iOS I get socket hung up

Any ideas what is causing this?

How much time passes between:

@twohill

Uploading assets

and:

@twohill

socket hang up

Also, does this happen every time? From the error it looks like the TCP connection was reset, so could be an intermittent problem?

It happened a couple of times and there wasn’t much of a delay.
I’ve tried again today and it’s working fine now; might have been related to the maintenance window yesterday…
