Magento 2.3.x Admin Panel keeps loading

Question

I have installed Magento 2.3.5-p1 and also tried 2.3.4-p2 on Centos 7, with Nginx & PHP-FPM, maria DB with following commands.

1. /var/www/magento < owner by MAGENTO:NGINX user (I have created a pool for magento:nginx)
2. find var generated vendor pub/static pub/media app/etc -type f -exec chmod g+w {} +
3. find var generated vendor pub/static pub/media app/etc -type d -exec chmod g+ws {} +
4. chmod u+x bin/magento
6. su magento

7.  bin/magento setup:install --base-url='https://www.example.com/' \
--base-url-secure='https://www.example.com/' \
--backend-frontname='' \
--db-host='localhost' --db-name='' --db-user='' \
--db-password='' --admin-firstname='example' \
--admin-lastname='Admin' --admin-email='' \
--admin-user='admin' --admin-password='' --language='en_US' \
--currency='USD' --timezone='UTC' --use-rewrites=1 --use-secure-admin=1 --use-secure=1

Once completed, my FRONTEND (home page) works absolutely fine, i just have 2 errors in the javascript console log:

[Error] Failed to load resource: the server responded with a status of 404 () (requirejs-config.js, line 0)
[Error] Refused to execute https://www.example.com/pub/static/version1594092941/frontend/Magento/luma/en_US/requirejs-config.js as script because "X-Content-Type: nosniff" was given and its Content-Type is not a script MIME type.

But when I open admin panel, I can login into it. However, after logging in it keeps loading. I have tried several methods available online such as:

1. rm -rf pub/static/* (except .htaccess) refresh page
2.  
php bin/magento cache:clean
php bin/magento cache:flush
php bin/magento setup:upgrade
php bin/magento setup:di:compile
3.
vi app/etc/di.xml <-- Change Symlink to Copy
rm -rf pub/static/*
refresh page
4. 
rm -rf var/*
bin/magento setup:static-content:deploy -f
bin/magento c:c
5. bin/magento cache:enable

I have tried to install it under both php-fpm and nginx group, also as nginx:nginx. Nothing works, admin panel just keeps loading.

What am I missing here?

Answer 1

Alright after days of troubleshooting I finally found the stupid issue that was related to open_basedir. However, i still don't know why that (Home Page) worked fine even when open_basedir in PHP was in affect. But only admin panel wasn't working.

So I disabled open_basedir in php.ini and reinstalled Magento 2, and I no longer had this issue.

$ vi /etc/php.ini

;open_basedir=/....

$ systemctl restart php-fpm

$ bin/magento setup:install --.....

It may be permission issues.
