You could try defining your topic as server.top, using a dot '.' to delimit words in a destination is also more consistent with how many other messaging systems define topic hierarchies. | Thank you, I've replaced slashes with dots and that's working well. P.S. I was not able to find topic you talked about. Search isn't working. Hope this issue is in plans to fix already.
