https://community.blueprism.com/t5/Product-Forum/Application-Detach-problem/m-p/93937#M43361 yes, I had a similar issue, where it was not connecting to a windows based java application. turns out that my antivirus blocked a connection of appman.exe started by BP to the application, When I enabled it was able to connect fine, but it still kept detaching. I added the applications as a trusted app, seems to be fine since then, but then again I am not sure your case is similar.  hope it helps.

After a while working it lost connection with the browser before process next record, so we connect again BP with browser using detach and attach and works fine one more time, but suddenly it lost connection and cannot attach browser no more. These issues happen only on Virtual Machine runtime. At a local machine it works fine. Has anyone faced this problem?
