What triggers SolusVM error "Connection Failed Debug Data: ERROR:4" ?

When this error occurs, the following error is displayed in SolusVM when opening Slave node page:

Connection Failed Debug Data: ERROR:4

AutoFTP restore does not start on the Slave node:

Could not connect to master server. Is the master online with port 5656 SSL open? exiting…


Cause for the SolusVM error

The main cause can be the ID Key in /usr/local/solusvm/data/solusvm.conf on Slave node does not match to the ID Key at SolusVM > Nodes > List Nodes > Edit Node Password

SolusVM creates the KEY:PASSWORD in the file after the SolusVM slave installation.

In order to get the KEY:PASSWORD pair we can do the following:

1. Log into SolusVM Slave Node via SSH.

2. Run the command to get the required information:

#cat /usr/local/solusvm/data/solusvm.conf


How to resolve SolusVM error "Connection Failed Debug Data: ERROR:4" ?

To fix this error, apply the following steps:

1. First, we have to log in to SolusVM admin panel.

2. Then copy ID Key from SolusVM at List Nodes > Edit Node Password.

3. After that connect to the affected slave node via SSH

4. And create a backup of original /usr/local/solusvm/data/solusvm.conf file on the affected slave node.

We can use the following command for this:

# cp -a /usr/local/solusvm/data/solusvm.conf{,.bkp}

5. Next, we have to paste this ID Key to /usr/local/solusvm/data/solusvm.conf replacing the original one:

# cat /usr/local/solusvm/data/solusvm.conf
