Forwarder not capable to download an app - ERROR HttpClientRequest

[corti77]

Good morning,

I have an app that is currently deployed in several servers via deployment manager.

Recently we install a new server and I add it to a specific server class in order to receive a small app.

For some reason, the app does not get deployed but others server classes do get deployed.

The error in the splunkd.log file is the following

could someone tell me what is happening?

the same app is already deployed in other servers without any issue.

thanks

I finally managed to solve it by running on the server the following command

splunk reload deploy-server
