Swarm: Failed to Ping

Hi Guys,

A few people with the same issue, however none with a resolution.

2 computers - -PC is the host running coordinator. REALTREE-PC, running swarm.

The coordinator recognises both computers - -PC & REALTREE-PC.

Upon light building, -PC is active, and REALTREE-PC log shows the attachment.

Firewall off has no effect.
