Upgrading the working splunk-devops-plugin from (1.8.2) to (1.9.4) breaks the connection, rollback to 1.8.2 restores it.

Test:

Upgrade plugin press "Test Connection" (splunk for Jenkins configuration) get error

Token:XXXXXX response:Forbidden

Rollback to version 1.8.2

Test connection success.

In a an adhoc Jenkins instance created to debug this we updated all plugins to the latest version with the latest Jenkins.

We also set the the variables http.proxyHost http.proxyPort https.proxyHost http.nonProxyHosts (per recent release notes)

In the Jenkins log we see the following.

com.splunk.splunkjenkins.utils.LogConsumer$SplunkClientError: Forbidden, http event collector token is invalid, status code:403
