I had a working collaboration between my organisations AGOL site and my organisations Enterprise, with the Enterprise receiving content (as copies) from AGOL on an hourly basis. It failed yesterday after 2 successful hourly syncs, and had been working for several weeks previously.
Now when the collaboration is setup again (using the previous settings) the Enterprise Workspace says joined however the AGOL workspace say 'not yet joined' and only the initial sync works.
All ports are allowing traffic, and I have tried creating brand new Workspaces and Groups at both end but to no avail. Does anyone have any fresh ideas please.
