The package is called its, as the message correctly said.

chart.yahoo.com is notoriously fickle (as we have seen from the tseries 
example using it).  Note that the first command (which gave me no error) 
also downloaded from there, so this is not going to be an access issue. 
I do get a 404 error on that URL (from two separate ISPs), but not if gdax 
is twice replaced by ftse.

I do think the posting guide makes clear this is an issue for the 
package maintainer, not for R-help.
