Trying to update address, timeout error

The group "gmane.org.user-groups.linux.golug" has had to move
its e-mail address.

Using the admin.gmane.io interface, when I try to update the golug list
address (to [email protected]) I get the error:

Request data update...Invalid list address [email protected]:
Initial greeting: (timed out while talking to server)

Is there a way around this?
