I will fix nginx configuration and server errors

Nginx breaking? I fix it.

I solve:

• 502 Bad Gateway errors (upstream issues)
• SSL certificate errors (expired, mismatched domain)
• 404 errors (wrong location block, file path issues)
• Reverse proxy configuration (app not reaching clients)
• Port binding issues (already in use, permission denied)
• Log analysis (why your site is down)

What I do:

- SSH into your VPS/server

- Diagnose the exact problem

- Fix configuration files

- Test and verify it works

- Provide clear explanation

What you need:

- SSH access (or server login)

- What error you're seeing

- What you're trying to run (Node.js, Python, static site, etc.)

What you get:

- Working Nginx config

- Root cause explanation

- Prevention tips

I work with: Ubuntu, CentOS, AWS, DigitalOcean, Linode
