Setting up Let's Encrypt with CloudFlare and dynamic IP

Setting up Let's Encrypt with CloudFlare and dynamic IP - If a page has internal and external outgoing links to redirecting URLs, it’s returning 3xx (301, 302, etc.) HTTP status codes standing for redirection. This issue means that the page does not exist on a permanent or temporary basis. It appears on most of the popular web browsers, usually caused by a misconfigured website. However, there are some steps you can take to ensure the issue isn’t on your side. You can find more details about redirecting URLs by reading the Google Search Central overview. In this article, we’ll go over how you can fix the Setting up Let's Encrypt with CloudFlare and dynamic IP error on your web browser. Problem :

My setup is as follows:

• Dedicated server (Linux) with dynamic IP address


• NO-IP domain name


• domain name


• When I want to access my system (server), I access my
  domain, which redirects me to my NO-IP domain which, in turn,
  redirects to a current IP address of the server.

I'd like to add encryption and DDOS protection to my system so I thought about setting up an SSL certificate and introducing CloudFlare services.

It is easy to setup CloudFlare, but I am really not sure if it's possible to setup up SSL via Let's Encrypt with the scheme I've created. I became lost in various types of SSL certificates (what exactly do I need?) considering several redirection that would occur.

The way I understood it is if I introduce SSL certificate from CloudFlare, I would only encrypt traffic from a user to CloudFlare but not from CloudFlare to the server. Am I right?

If I am going to get Let's Encrypt certificate, I would need to install it on my server, but how do I get one if there are several redirects involved and I have a dynamic IP address? How would it work with CloudFlare?

Solution :

You can create a self-signed certificate on the server, and use that with CF's Full, but not Full (strict) SSL setting. I don't know if you'd have to create a new self-signed certificate each time the IP changes though.
