How to resolve frequent license issue errors such as "In handler 'localslave': editTracker failed" on Search Head Cluster?

We have Search Head cluster with 3 nodes. We try to point all these nodes to my License master .
When I tried to do as the master Uri from the SH members/Deployer UI it showing error message:

"Bad Request — In handler 'localslave': editTracker failed, reason='WARN: path=/masterlm/usage: invalid signature on request from ip=x.x.xx.xx " 

I have manually updated the same from CLI in server.conf, it worked but slaves are not contacting frequently license master . After 24 hrs i am getting license expired message on Splunk Web. Again, I have removed the master uri stanza and placed the same back and restarted. it worked

How to fix this one ?

Also I have done telnet from my search head members to license master and it connected without any issues.

The root cause for the issue is pass4SymmKey present in server.conf

[general]
pass4SymmKey = test
serverName = x.x.x.x.x

When ever any server you tried to point to licensemaster , The LM pass4symmkey should be same as the server which you want to point .

this one implemented in prod environment and working fine without any issues .

Hi sivapuvvada,

Please try running the following CLI command on each slave:

splunk edit licenser-localslave -master_uri https://{Lic_Master:mgmt_port}

To check the list of license slaves, run this command on the license master:

splunk list licenser-slaves

Hope this helps. Thanks!
