I suspect it will as Port 8199 is used once the resource is logged on and the automate application starts. Port 8181 is the port that the login agent and application server use to communicate until such time that the runtime resource is logged on. To check communication, Telnet from the server to the resource on 8181 and vice versa and see whether that is blocked, if it is then that is your problem. If in doubt about the port used, check the file LoginAgentService.config which is located in C:\ProgramData\Blue Prism Limited\Automate V3 There will be an entry similar to this. 8181 Regards, Steve Thu, 07 Dec 2017 21:08:00 GMT SteveBoomer 2017-12-07T21:08:00Z https://community.blueprism.com/t5/Product-Forum/Resource-PC-is-offline/m-p/46996#M2841 Hey, The resource PC in control room is showing offline.
