I am facing errors on that license master is low, what could be the issue?
My LC version is 6.5.1 and Search head is 7.2.1
This could be the issue if the LC master and search head are not with the same versions.
Please upgrade your Splunk environment and also please see that you are forwarding the data from the LM to the index cluster which is highly recommended.
Are you forwarding the data from the LM to the index cluster as per best practice? If not, you will not be able to search the license data from the SH.
is it possible to share the screenshot?
