Trying to install ifs-monitoring on a remote deployment 23R1, SU1. Is there any URLs that needs to be whitelisted? We see error on the monitoring-grafana pod and if trying to reach:

https://grafana.com/api/plugins/repo/grafana-polystat-panel

on the server, it is not able to. 

Is there any other URLs that are used that potentially needs to be whitelisted for use of grafana/prometheus/kibana?

Error messages from log files for reference:
 

Failed to load logs: container "elasticsearch-curator" in pod "monitoring-elasticsearch-curator-28209900-tvknk" is waiting to start: trying and failing to pull image

Reason: BadRequest (400)
