My pom file plugin is:

@54754N4,

Just review your local configuration ...

[MrAlucardDante]

@54754N4 Did you manage to find what was causing the issue ? I am experiencing it too.

@bnasslahsen What do you mean by

Just review your local configuration ...

This is not really helping

[bnasslahsen]

It means we can do nothing for it as well. It's local configuration issue - not reproducible in our end!

[MrAlucardDante]

So I managed to get rid of the error by changing the management port to another port and configuring springdoc to use the management port, like it is mentionned in the documentation, although I'd like to use the same port, but I can live with that.

But now I get a 401 because I am using Spring Security to secure the actuator endpoints and my API.

I tried disabling Spring security with http.authorizeHttpRequests().anyRequest().permitAll(); but now I get a 404.

Any ideas ?
