Deployment Architecture

Apps push not working - Why did it fail to verify HMAC signature?

Hi,

after an upgrade from 7.3 (to 8.1.0 and then) to 8.2.5, there are some errors on splunkd.log.

SH1: 

SH2 and SH3:

  • ERROR DigestProcessor [107884 TcpChannelThread] - Failed signature match
  • ERROR LMHttpUtil [107884 TcpChannelThread] - Failed to verify HMAC signature, uri: /services/server/health/splunkd/local?output_mode=json 

Besides, if I try to push some apps' configurations, it doesn't work.

The environment consists of a Deployment Server/Cluster Master (same instance), 3 Search Heads and 2 Indexers.
All the files in server.conf in the DS/CM and SHs have the same pass4SymmKey:

 

 

 

[clustering]
master_uri = <my_master_uri>
pass4SymmKey = <my_crypted_pass>

 

 

 

 

Does anyone have an idea about what's wrong?

Thanks in advance
