[Swift-user] Channel Timeout on Beagle?

[Matthew Shaxted]

Hi Swift Users:

I am running some studies on Beagle using Swift, and experiencing a strange error. The Swift scripts run great on cloud and on the Beagle login node, but seems to be timing out for some reason.

Does anyone have insight into the cause of this? Thanks for any help.

Below is the error I am getting:
