Why does the Laravel admin give a 500 Internal Server Error?

Question

Laravel

Good day to all!
Guys, the thing is this .. I stopped accessing the admin panel using the site.com/admin link after I reinstalled the OS at home =) gives an error 500. Before that, everything worked.
There is no error in the logs at /storage/logs/laravel.log; rights exhibited 777 - all in vain; I checked all the files with the backup - everything is in order; and rebooted too. Tried using different browsers, same result.
Later I thought of going deeper site.com/admin/pages or site.com/admin/all, etc. they follow these links and everything works fine, but site.com/admin does not want to. Wonders.
Before that, it used to happen, the chrome browser in the admin panel broke and gave errors. Look like that's it.
Thank you!

Answer 1

1) Enable in .env
Should display error details on the screen (500 - says nothing).
2) If not, then it may be a web server error. (for example, incorrect htaccess).

Answer 2

Well, there are no telepaths here, so turn on the debug mode and see what the problems are.

Answer 3

Guys, nevertheless, the problem was, it seems to me, in htaccess, now I once again decided to set permissions to 755 for all files, but only through ftp and everything worked, before that I changed it through the terminal.
In general, what should be the permission on files and directories?
before that, I always put 755 on directories, 644 on files.
