1. Describe your incident:

I’ve just installed a fresh installation of Graylog to be able to receive alerts from Wazuh Manager, via a raw/plaintext TCP input. I’ve connected both instances correctly but I’m receiving these errors, when I try to “Show Received Messages”:

• OS Information:
  Ubuntu Server 22.04
• Package Version:
  Graylog v4.3.11+b48cf45

3. What steps have you already taken to try and solve the problem?

I’ve just repeated the same steps above and I also tried to delete the index graylog_0 on Wazuh’s Indexer.

Was able to solve this by editing server.conf and changing the default elastic index prefix name.

Thank you, nevertheless!
