Remote data access not working

SUGGESTED

Hello,

Our Sage50 setup includes 5 companies with multiple users in each company. One company was successfully shared yesterday by the data owner, with a second user able to log in and work. The second user logged out for a time and when they tried to log back in about 2 hours later got the message that their user ID was already using the company and they could only access in read-only mode. The data owner had also logged out for the day in the meantime (leaving the company in shared mode) so the company was not open at all when the second user tried to log back in. This morning the data owner could not get access to the company, also receiving the message that the second user's ID was already using the company (they were not). We had to restore the company from a back up to be able to open it again.

We had followed the steps in article 105572 to migrate the data and in 105521 to set up users, and it seemed to be working initially. I've been searching the knowledgebase and forums for more specific information on best practice for using remote data access in setups like ours but can't find anything that really lays out what that would be. Is it a Sage ID issue, in that once an ID is used on one workstation it's only recognized at that same station (some info I found seems to point to this)? I'd really appreciate some help so that our multi-company multi-user setup can successfully use remote access.
