Redirect is looping, magento 2.4

Job Title: Magento 2.4.3 Redirection Issue Troubleshooter

Job Description:

We are seeking a skilled Magento 2.4.3 developer/system administrator to help resolve a persistent redirection issue that is preventing access to the website. The issue started after a redirect rule was added in the Mirasvit Advanced SEO extension. Despite multiple troubleshooting steps, the website is still facing a redirection loop and returning the error: `ERR_TOO_MANY_REDIRECTS`.

Key Responsibilities:
- Diagnose and fix the `ERR_TOO_MANY_REDIRECTS` error that occurs when accessing the website.
- Analyze and ensure the proper functioning of Magento configurations, particularly regarding base URL and redirects.
- Review server settings and Magento environment for potential issues, particularly related to Plesk 18, DNS, and caching.
- Restore Magento functionality to normal, ensuring access to both the frontend and the backend (admin panel).
- Review and adjust `.htaccess`, URL rewrite rules, and Magento's internal redirect configurations.
- Investigate potential session or cookie-related issues causing redirects to loop.

Required Experience:
- Strong experience with Magento 2.4.3 and its configuration management.
- Deep knowledge of web servers (Apache/Nginx) and PHP configurations.
- Experience with troubleshooting redirection issues in Magento, especially related to custom modules and SEO tools like Mirasvit.
- Familiarity with Plesk 18 and its impact on server configurations (ownership changes, automatic updates, etc.).
- Ability to work with PHP-FPM, MySQL, and cache systems within the Magento environment.

What Has Been Done Already:
1. Database Restoration: Restored the database to a known working state to ensure no data corruption.
2. Code Restoration: Wiped and restored all Magento code from a clean backup, including cleaning `app/code` and `vendor` directories.
3. Configuration Files: Reviewed and restored necessary configurations in `.htaccess` for proper URL handling and redirection.
4. Magento Permissions: Corrected ownership and permissions for all relevant directories (`var`, `generated`, `pub/media`, `pub/static`, etc.).
5. Cache Management: Ran cache cleaning commands (`bin/magento cache:clean` and `bin/magento cache:flush`).
6. Indexer: Ran the `bin/magento indexer:reindex` command to ensure proper data indexing.
7. Web Server Configurations: Verified that Apache and Nginx configurations are set up correctly and `mod_rewrite` is enabled.
8. Log Review: Examined system and exception logs for potential error sources, including missing products or misconfigurations.
9. Base URL Check: Ensured that base URLs are correctly configured in `core_config_data`.

Suggested Next Steps:
- Session/Cookie Management Review: Investigate potential session handling or cookies being set incorrectly by the server or Magento.
- SSL/HTTPS Configuration: Confirm that SSL redirection is not conflicting with Magento settings or affecting access.
- Magento Redirect Configuration Review: Check for any Magento-specific redirect rules causing the loop.
- DNS and CDN Configuration: Verify DNS or CDN-related settings that might be introducing incorrect redirects.

Skills Required:
- Magento 2.x development
- PHP, MySQL, Apache, Nginx troubleshooting
- Plesk server management
- SEO and URL rewrite handling in Magento

Timeline:
- Immediate fix required, please apply only if you can start right away.

Additional Information:
- The site is currently not accessible through any URL (including the admin panel).
- The issue is suspected to have been caused by Plesk's automatic updates or ownership changes, as this happened shortly after an automatic Plesk update.
