[edited on 19th june] The question is not regarding the content of the logs, but why logs doesn't not appear in my symfony profiler
My symfony profiler doesn't display any error log but my php built-in-server seems to catch them and display them in my terminal.
To run my built-in web server, i'm using the following command: php bin/console server:run with no extra parameters
the output in my terminal is something like:

When I check my symfony profiler, i got this empty screen:

(source: i.ibb.co)
I remember long time ago, I run a command in my terminal to change the verbosity, but I'm unfortunately unable to remember which one was it to revert it. And I think this is the reason why the terminal is displaying the log info instead of my symfony profiler
Is there someone who can help me ?
There is no error shown in your output from terminal. It states that authentication failed and it won't let your HTTP request pass security component. That's why you are getting HTTP response
401 Unauthorized.You have issue in your application security config which is not letting any request through. That's why Symfony profiler is empty and why you cannot reach the website. Though this is not an
Exceptionwhich could be thrown. It's simply required behavior based on your particular config and sent request.Also any change to verbosity of the command (parameter
-v[vv]) is not permanent and is relevant only during the run of that particular command.
