Hi All,

I am facing this issue, Agent Client Collector (ACC) mid-less is successfully installed and registered on the Windows server. The ACC agent appears as Up in ServiceNow, but Host Data Collection fails.

The following error is coming;
ACC-1510 – Unable to download ACC plugin

error getting assets for check:
error downloading asset: unexpected EOF​

Anyone face this issue earlier?

Thanks in advance

Hi @Aman Trivedi1 ,

 

As you’re running MID-less, the agent talks straight to the ITOM Gateway, so that’s the link I’d check first. What makes me think that is the agent showing as Up while the plugin download fails. Registration and heartbeat are tiny calls, so they get through fine, but pulling down the plugin is a much bigger transfer, and “unexpected EOF” usually means the connection got cut off halfway.

 

Before doing any fancy stuff, try restarting the agent. That will kick off the asset download again, so once it’s back up, try collecting the host data once more. If it was just a dropped connection, that may sort it.

If it still fails, and there’s a proxy, firewall or SSL inspection between that server and the gateway, I’d look there first, as those like to interfere with larger downloads.

If the issue still persists please do share the logs so that we can get more insights to debug.

 

Hope this helps, if it helped you please do mark it as helpful and accept the solution.

 

Thanks,

Vishnu

Review network connectivity between agent and MID Server or ITOM Gateway

@Aman Trivedi1  as per this KB -  Agent Client Collector (ACC) error codes and troubleshooting - Support and Troubleshooting

 

Issue is network connection between AGENT and ServiceNow ITOM Gateway to which agent connected for Download. Review Conenction with help of n/w team and see when and where and why packets are dropping or connection is getting aborted.

 

Regards
