Hello Team Galaxy 

trying to share/ forward dataset history from user 1 ( running on a local instance,Scrn.1) to user 2 (running on cloud amazon ec2 instance,Scrn.2) and vice-versa, error:- user is not a valid galaxy user. getting this error while both the users are logged into system and both the instance's are running normal.

insights of team will be very helpful.

Thanks
