Received "open tunnel event" with host id: null

[former_member732517]

Since 2 days I can't open a connection between Cloud Connector and SAP Business Application Studio.
When I try to create a SAP Fiori Freestyle Project using a source link to the Cloud Connector I have this error on the log file ljs_trace.log

I don't understand why I have "host id: null" on the line
#Received "open tunnel event" message (packet type: 1 (open tunnel)) for tunnel id account:///2ba2792f-4a52-40f6-8329-3d1199c47b37 and host id: null

Hello Samuel Bertin,

I'm currently facing the same problem.
Have you been able to solve the problem?

Kind regards
