I am now seeing the same issue.
RHEL 9
Installed wazuh 4.7.5 with the all-in-one install script last week, had been working perfectly.
Today the package updates upgraded wazuh-dashboard, wazuh-indexer and wazuh-manager to 4.8.0
Now wazuh is broken. Although all wazuh processes are running, accessing the server displays only a 500 server error
Anyone else?
