How to Fix SolusVM error “Connection Failed Debug Data: ERROR:4”

Following are the steps to fix this error:

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}
3. 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

4. Now we can copy the PASSWORD (second part of /usr/local/solusvm/data/solusvm.conf file) and Paste PASSWORD to ID Password field at List Nodes > Edit Node Password.
