# Test ACC connectivity

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

Release version: Brazil  
Updated October 23, 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_c12_zgw_3kc}
   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 \[sys_attachment\] table.  
   See the preceding image for the location of the Size bytes information in the Attachments table.
If the command output doesn't match the Attachments table entries, the proxy configuration must be corrected.
