Task registration error when performing VM operations

Problem

When starting, rebooting, or creating a backup of a virtual machine (VM), the task does not appear in the Task queue section. The web interface does not show any error messages, but all VM operations are ignored.

The following errors appear:

• in the logs of the taskmgr container:
  
  Example error

  Catch exception while processing: No such file or directory [system:2 at .../boost/asio/detail/reactive_socket_connect_op.hpp]

  or
  
  Example error

  error: wait timeout reached
  GET http://consul:8500/v1/kv/proxy/?recurse&index=...

• in the file taskmgr_worker.log:
  
  Example error

  Task registration error: Operation canceled [system:125]
  Response body '{"error":{"code":5233,"id":"VM-5233","msg":"Task registration error"}}'

The issue may coincide with scheduled backup startup, but it is not tied to any specific VM or action.

Solution

To resolve the issue:

1. Connect to the server with the platform via SSH. For more information about connecting via SSH, see Workstation setup.
2. Restart the taskmgr container:
   

   docker restart taskmgr

3. Check the VM operations. If the issue persists, restart the platform:
   

   vm stop && vm start
