SQLSafe xp_ss_restore Could not retrieve version from SQL Server

I recently inherited a system which uses the backups of a production system to populate a test environment for devs.  They do a refresh every few months, and when they tried it a couple days ago, it failed.  I am not able to tell from the error message "Could not retrieve version from SQL Server" what is actually failing.

xp_ss_restore did not complete.  An error(0,1) was encountered.  Please check the parameters and their values. [v7.4.0.86]

SQLsafeCmd output:

The event viewer has similar output:
