There are several scenarios when your vSphere Bitfusion client might be unable to connect to the vSphere Bitfusion servers in your cluster.

Problem

When trying to connect a vSphere Bitfusion client to the servers in your cluster, the connection fails. Typically, you see an error message that is similar to the following example.

Error querying server 10.115.27.120:56001:
Get https://10.115.27.120:56001/query: x509: certificate signed by unknown authority
Unable to contact any of the existing servers: 10.115.27.120:56001

Cause

  • When you are moving or cloning a vSphere Bitfusion client to a new vCenter Server instance.
  • When you install new vSphere Bitfusion servers, resulting in a new cluster creation, and you use your old vSphere Bitfusion clients.
  • When you have an invalid vSphere Bitfusion server in your cluster.

Solution

  • If you have an invalid vSphere Bitfusion server in your inventory, by using the vSphere Bitfusion plug-in, remove the server from the cluster.

    For more information, see Remove a vSphere Bitfusion Server.

    If the server cannot be removed from the inventory by using the vSphere Bitfusion plug-in, in the terminal of a running vSphere Bitfusion server, run the bitfusion removenode command.

  • Verify that all steps during the vSphere Bitfusion client enablement process are completed.

    For example, verify that the virtual machine of the vSphere Bitfusion client is powered off during the enablement process.

    For more information, see Enabling the vSphere Bitfusion Client in the VMware vSphere Bitfusion Installation Guide.

  • In the virtual machine terminal of the vSphere Bitfusion client, run the following commands.
    1. rm ~/.bitfusion/client.yaml
    2. rm ~/.bitfusion/servers.conf
    After the client.yaml and servers.conf are deleted, reenable the vSphere Bitfusion client.

    For more information, see Enabling the vSphere Bitfusion Client in the VMware vSphere Bitfusion Installation Guide.

  • If none of the previous steps resolve the issue, create logs from a vSphere Bitfusion server and send the support bundle to VMware support.

    For more information, see Create vSphere Bitfusion Server Logs.
