Well ... it seems that there is already a fix in place for "REST not 
supported" error ... BUT ... it is expecting a return code of 501 and 
not 502 which you are getting.

For now, see if switching the line

             except ftplib.error_perm, reason:
                 if str(reason)[:3] == '501':

to

             except ftplib.error_perm, reason:
                 if str(reason)[:3] == '502':

and see what you get.

Sorry for chuckling, it just reminds me of some old tv series.  "missed 
it by *that* much"
