Troubleshooting cluster connection

Introduction

A cluster connection problem generally means that either the server or a client window is frozen.

Master can’t connect to slave’s VRDaemon

In the master’s log, you see:

[X] ConnectToDaemon:Failed to connect to '192.168.1.2'.Is the VRDaemon running?
[X] RemoteStart: Failed to connect to daemon.

- Make sure you have the VRDaemon running on all the clients.

- Try disabling the firewall from both the server and the client.

- On the master, use Putty to try a connection to the client’s port 9998:
(You can find the machine Host Name and IP address in the VRDaemon start message)

If Putty can’t connect to the daemon, you will get the following error:

In this case, if you used the machine Host Name, try using the IP Address instead.
If Putty still can’t connect, contact your system administrator.

If Putty can connect to the Daemon, you will get the following message:

Client can’t connect to server

If the client can’t connect to the server, you will see this in the client’s log:

[ ] Connecting data socket..
[ ] Connecting swaplock socket..
[X] Cluster Client: Connection timeout, exceeded maximum connection time of 60 seconds!
[X] Could not connect to server, quitting !

In the server's logs you will see:

[ ] Server starting to wait for clients..

This is probably a network issue.

- Try disabling the firewall from both the server and the client

- A user reported that manually adding the application's .exe to the firewall's list of approved apps removed the issue for all the apps.

- With Putty, try a connection from the client to the master on port 9999 (in Raw mode) :

If Putty can’t connect to the server, you will get the following error:

This means that your network has probably a problem. Ask your system administrator for help.

 

If the connection occurs normally, you should see a window like:
