Pull self-signed certificates from the ServiceNow install server, instead of waiting for the scheduled MID Server synchronization.

## Before you begin

* Ensure that the self-signed certificate is placed in a .zip file on the MID Server in the following location: agent\\static\\cert
* Ensure that the certificate authority is part of the agent host's truststore, as the certificate chain is validated before the customer plugin signature.
* Role required: agent_client_collector_admin
{#manually-sync-certificates__ul_evp_bly_fgc}

## About this task

The MID Server checks for updates once each day, or after being restarted.

## Procedure

1. Navigate to AllAgent Client CollectorMID Servers.
2. Select a MID Server.
3. In the Related Links section, select Trigger ACC certificate sync.
4. Restart the MID Server.

## Result

When an agent fails to perform a certificate check, the agent synchronizes certificates available on the MID Server. Synchronization is carried out for certificates on the ServiceNow install server and the self-signed certificates placed in the .zip file on the MID Server's agent\\static\\cert folder. Certificates are downloaded by the Agent Client Collector if the agent fails to validate a check definition's associated plugin assets.
