reverse-proxy configuration issue when running from different browsers
February 12, 2024 08:48PM
Hello,

I kindly request help in how to resolve the following problem I am experiencing on my new nginx server configuration.

Basic information:
Installed Nginx ver 1.8 on Ubuntu 20.04 LTS
Objective: to use Nginx as a reverse-proxy server.
I host my own sites, one public IP.

I have two webservers on my internal network.
All http and https traffic is natting to my Nginx server
Nginx Reverse-proxy, passes traffic to specific webserver depending on domain-name (domain-name.conf)
domain-name.conf resides in /etc/nginx/sites-enabled (see attached file)

Problem:

My installation is partially working.
For example the attached .conf works well when using Firefox, but when using Safari or Chrome, it does not work.

Other situation I am experiencing is with another similar .conf file for another domain-name (same file as attached but different servername, ssl path, and proxy-pass IP)
It works well when using Safari and Chrome but it does not well when using Firefox.

Any suggestions to correct this problem?

Thanks.

Rich

To troubleshoot:

1. Check Nginx error logs for any specific errors.
2. Ensure SSL certificates are configured correctly for each domain.
3. Verify DNS settings for each domain.
4. Test server configuration with online tools like SSL Labs.
5. Try adjusting SSL protocols and ciphers in Nginx configuration.
6. Consider browser-specific configurations or caching issues.

These steps should help identify and resolve the inconsistencies in browser behavior.
