I am trying to run a jenkins job to flush dispatcher cache and getting below error.
<p>You don't have permission to access /dispatcher/invalidate.cache
on this server.</p>
<p>Additionally, a 403 Forbidden
error was encountered while trying to use an ErrorDocument to handle the request.</p>
The forbidden(403) error means the Publish IP is not allowed to make flush requests to the dispatcher. Basically, the dispatcher checks all the allowedclients and if publish IP is not there, It does not allow any requests from that IP to be run on the dispatcher.
Although it seems like a user permissions issue but Its related to allowedlist of IP's
