## Symptoms

- Web services communication failure in Multi-Domain Management Server Domain.

## Cause

There are duplicated entries in the Web Services configuration file: *$MDSDIR/conf/mdsdb/webservices_cmas_ports.conf*.

When a Domain (CMA) starts, different processes read the *webservices_cmas_ports.conf*file.

For example, CPD sends a web service request to the FWM web service port that it reads from the file.  
When there are multiple entries for the same Domain, the FWM may listen on a different port that it reads from the same file.  
In this case the CPD daemon fail to communicate with the FWM daemon.

## Solution

[Contact Check Point Support](https://www.checkpoint.com/support-services/contact-support/) to get a Hotfix for this issue.

A Support Engineer will make sure the Hotfix is compatible with your environment before providing it.  
For faster resolution and verification, collect these files:

1. [CPinfo](https://support.checkpoint.com/results/sk/sk92739) file from the Management Server involved in the case.
2. [CPinfo](https://support.checkpoint.com/results/sk/sk92739) file from the Security Gateway / each Cluster Member involved in the case.

**Hotfix installation instructions:**   
Refer to [sk168597 - How to install a Hotfix](https://support.checkpoint.com/results/sk/sk168597).
After the hotfix installation, run these commands:  

1. `$MDSDIR/bin/rm_dup_websvc_cmas_entries`
2. `mdsstop`
3. `mdsstart`

The command saves a backup file before editing in this format:  
*webservices_cmas_ports.conf_yyyy_mm_dd__hh:ss:ms*   

If an error occurs:

1. Copy the backup file to *$MDSDIR/conf/mdsdb/webservices_cmas_ports.conf*
2. Run: `mdsstop`
3. Run: `mdsstart`
