Splunk 9.3 - WebUI module won't restart or start.

[andy_itperson]

I've had a working Splunk instance for a month, but post patch it refuses to start the webUI.

Where I would either start splunk (no issues) but the UI won't work.

I've tried:

Checking web.conf
Checking ports
Checking firewall-cmd

Checking permissions.

When restarting webserver via ./splunk restart splunkweb the splunkd.log shows it restarting then instantly stopping the module - what could be doing that?

Splunk Web and interface issues

Date resolved	Issue number	Description
2024-07-09	SPL-256902	Splunk is crashing with "Crashing thread: WebuiStartup" when TLS is used for Splunk Web with an empty DNS under "X509v3 Subject Alternative Name" field of the certificate

This got posted first in 9.2.x and shows fixed in 9.4.0 but I don't see it listed as known or fixed in any 9.3.x release docs.  Might be something to ponder.
