Caused by: org.springframework.boot.web.server.WebServerException: Unable to start embedded Tomcat at org.springframework.boot.web.embedded.tomcat.TomcatWebServer.initialize(TomcatWebServer.java:142) ~[spring-boot-3.0.1.jar:3.0.1]

[InglisDav]

In the sprint boot upgrade I had a problem when running the application, because the SSL certificate was not found (It shows me to make sure that the certificate exists but it is created) and tomcat server could not be started.
I already tried adding the location to the tag but it does not work, example: <keyStore id="defaultKeyStore" location="/certs/KeyStore.p12" password="${KEY_STORE_PWD}" type="PKCS12"/>

Would I have to add a new ssl library for this new version?, or the name of the certificate change?

I appreciate any comments, Here I put the information that I am using:

Java 17
'org.springframework.boot' version '3.0.1'
Gradle 8.1.1

I don't think the failure is related to SSL.

This indicates that something has already registered a URL stream handler factory which prevents Tomcat from doing so. Unfortunately, it's impossible for us to tell what that is with the information that you've provided. I would recommend running your application with a debugger attached and a breakpoint on java.net.URL.setURLStreamHandlerFactory. That should allow you to identify the other component that's registering a factory.

If this does not help and you would like us to spend some more time investigating, please spend some time providing a complete yet minimal sample that reproduces the problem. You can share it with us by pushing it to a separate repository on GitHub or by zipping it up and attaching it to this issue.
