  • Parallels Business Automation - Enterprise


The Provider or a customer cannot log in to the POA or PBA Control Panel or switch between the POA and PBA Control Panels. The Control Panel is not completely accessible or shows error messages like the ones provided below:

Fatal error

An unforeseen error occurred

Billing is not available now

System error

Server BM_Container is not available

Service Unavailable The corresponding service is not available at the moment, try it within 2-3 minutes.

This article describes basic troubleshooting steps for when the Parallels Automation Control Panel is down or is giving an internal server error.


There are many possible reasons for Parallels Automation Control Panel unavailability:

  1. Stopped or hung servers

  2. Stopped or hung services

  3. Lack of resources (e.g., memory, diskspace) on servers

  4. Network connectivity issues (firewall)

  5. Misconfigured services

  6. Expired license

Find more details about checking all of the above reasons for the problem and troubleshooting actions.


First, identify which Control Panel is causing problems - POA or PBA.

Usually, all users log in to the POA Control Panel first and then switch to the PBA Control Panel, so in most cases, if a user cannot log in to the Control Panel, it means they cannot log in to the POA CP.

Follow the steps in the Parallels Knowledgebase article POA Control Panel is down or inaccessible: Known Issues and Troubleshooting to resolve problems with POA Control Panel unavailability.

If users experience problems with switching from POA Control Panel to PBA, then the first step to troubleshoot the problem is to check if it is possible to log in to the PBA Control Panel directly.

Use the Parallels Knowledgebase article PBA Control Panel is down or inaccessible: Known Issues and Troubleshooting to resolve problems with PBA Control Panel unavailability.

If opening PBA Control Panel directly works and it is still not possible to switch to it from the POA Control Panel, then use the Parallels Knowledgebase article Switch from POA Control Panel to PBA does not work: Known Issues and Troubleshooting to resolve the problem.
