Problem

-- User unable to log into B2Bi tools client, TSclient, B2Bi System Manager

-- Error on client: "System not available yet"

-- Error in Integrator trace: "Could not connect to system. Please check if the system is fully started"

-- The plain HTTP port/server for the B2Bi UI (default port 6080) has been disabled

-- Only the HTTPS port/server for the B2Bi UI is enabled (Default 6443)

Resolution

The solution is to enable the default HTTP port for the UI again:

1. Log into the UI
2. Go to "System Management"
3. Related Task -> "Configure UI connection"
4. Enable "UI connections made via HTTP"
