# Test ACC connectivity

# Test Agent Client Collector connectivity {#ariaid-title1}

Release version: Australia  
Updated March 12, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Test the Agent Client Collector (ACC) connectivity to identify any proxy issues.

## Before you begin

Note:  
SSL inspection isn't supported for DEX.

Role required: agent_client_collector_admin

## Procedure

1. Gather the following information to test communication between the ACC and ServiceNow shared services:
   1. Copy CNC certificates from the agent to a new folder:  
      {#test-acc-connectivity__table_x3y_lvn_nfc__entry__3}

      | OS | Copy from | Paste to |
      |-|-|-|
      | Windows | C:\\ProgramData\\ServiceNow\\agent-client-collector\\config\\cert\\cnc | Any temp folder |
      | macOS | /Library/Application Support/ServiceNow/agent-client-collector/cert/cnc | Any temp folder |
      [ ]

      {#test-acc-connectivity__table_x3y_lvn_nfc}
   2. Copy the gateway URL based on your location:  
      * AMER (Americas): itomcnc-prod-gateway.amer.sncapps.service-now.com:443
      * EMEA (Europe): itomcnc-prod-gateway.emea.sncapps.service-now.com:443
      * APAC (Asia Pacific): itomcnc-prod-gateway.apac.sncapps.service-now.com:443
      {#test-acc-connectivity__ul_xt5_jm2_mfc}
   3. Navigate to Allsys_attachment.list.
   4. Under Attachments, select File name in the drop-down menu and search for acc-dex-common.tar.gz.
   5. Retrieve the following parameters:  
      * Record sys_id
      * Hash id

      {#test-acc-connectivity__ul_thm_2t2_mfc}
   {#test-acc-connectivity__substeps_x1w_zr2_mfc}
2. Test the connection by running one of the following commands from the temp folder that you created:  
   * Without Proxy: `curl --verbose --output acc-dex-common.tar.gz --cert cnc_chain.crt --key priv_key.pem https://<ITOM-Gateway-URL>/content/v1/assets/<attachment_sys_id>/<hash_id>`
   * With Proxy: `curl --verbose ---proxy <HOST_NAME>:<PORT> --output acc-dex-common.tar.gz --cert cnc_chain.crt --key priv_key.pem
     https://<ITOM-Gateway-URL>/content/v1/assets/<attachment_sys_id>/<hash_id>`
   {#test-acc-connectivity__ul_csr_5m2_mfc}  
   The command output is generated.
3. Confirm that the Content length in the command output matches the Size bytes in the Attachments table (sys_attachment).  
   See the preceding image for the location of the Size bytes information in the Attachments table.
Fix your proxy issues if the command output doesn't match the Attachments table entries.
