Cloudflare err_ssl_protocol_error - Fix it Now ?

This article covers methods to resolve Cloudflare ERR_SSL_PROTOCOL_ERROR. Basically, this error happens as a result of a number of reasons that include wrong DNS settings, SSL mode, TLS version or issues with SSL certificate. 


To fix this error,

1. If you are not the site owner, contact the site owner and let them know you are having issues accessing their site.

2. The domain name has not fully been set to use Cloudflare yet. Check to see if there are non-Cloudflare nameservers that are conflicting with the assigned Cloudflare name servers.

3. You are signed up for Cloudflare, but you have set a DNS record to :grey:. If you have a subdomain or hostname and that serves HTTP/HTTPS traffic, we would advise that you :orange: this DNS record to take advantage of Cloudflare’s security and performance features. See What subdomains are appropriate for :orange:/:grey: clouds? 69

4. The Free Universal SSL certificate hasn’t yet been deployed, :grey: (deactivate) Cloudflare so that your website can continue to use your origin’s SSL certificate. Wait 24 hours and :orange: (activate) Cloudflare again to see if your SSL certificate has been successfully deployed.

5. You have some conflict with TLS 1.3, disable it and see if you still encounter the error.

6. You have selected Full SSL (strict) under your SSL/TLS app, but your origin does not have a valid certificate (i.e., it is expired, self-signed, or not issued by a trusted CA). Temporarily select another SSL option until you have a valid origin certificate in place.

7. Try to look at developer web console (firefox Ctrl+Shift+K) - anything interesting under Security tab.

8. Also, Try to run the command curl -vk on the affected domain.

Cloudflare 502 error - Fix it Now ?

The domain name is not pointing to the correct IP or it does not point to any IP this problem may happen. Also, DNS propagation could take some time to make changes in DNS setting. It may take 24 to 48 hours to make reflect which is dependent upon the TTL defined per record on the DNS.

2. server down

The origin server is not reachable, this may due to the server is down for some reason or there is no communication to the server given.

3. Firewall blocks

A firewall interrupts the communication between the edge servers and the origin server. This may be caused by security plugins of your CMS.

As a part of DDOS protection and mitigation process or due to some strict firewall rules servers can be blocked from accessing the original server.

Boost performance of Websites using Cloudflare - Tips to implement it

This article covers how to improve the performance of Websites using Cloudflare. Website speed has a huge impact on user experience, SEO, and conversion rates. Improving website performance is essential for drawing traffic to a website and keeping site visitors engaged. 

Along with the caching and CDN, Cloudflare helps protect your site against brute-force attacks and threats against your website.

Cloudflare has the advantage of serving million of websites and so can identify malicious bots and users more easily than any operating system firewall.


CDNs boost the speed of websites by caching content in multiple locations around the world. CDN caching servers are typically located closer to end users than the host, or origin server. Requests for content go to a CDN server instead of all the way to the hosting server, which may be thousands of miles and across multiple autonomous networks from the user. Using a CDN can result in a massive decrease in page load times.


How to get started on optimizing website performance with Cloudfare CDN (content delivery network)?

1. Optimize images

Images comprise a large percentage of Internet traffic, and they often take the longest to load on a website since image files tend to be larger in size than HTML and CSS files. Luckily, image load time can be reduced via image optimization. Optimizing images typically involves reducing the resolution, compressing the files, and reducing their dimensions, and many image optimizers and image compressors are available for free online.

2. Minify CSS and JavaScript files

Minifying code means removing anything that a computer doesn't need in order to understand and carry out the code, including code comments, whitespace, and unnecessary semicolons. This makes CSS and JavaScript files slightly smaller so that they load faster in the browser and take up less bandwidth.

3. Reduce the number of HTTP requests if possible

Most webpages will require browsers to make multiple HTTP requests for various assets on the page, including images, scripts, and CSS files. In fact many webpages will require dozens of these requests. Each request results in a round trip to and from the server hosting the resource, which can add to the overall load time for a webpage. 

4. Use browser HTTP caching

The browser cache is a temporary storage location where browsers save copies of static files so that they can load recently visited webpages much more quickly, instead of needing to request the same content over and over. Developers can instruct browsers to cache elements of a webpage that will not change often. Instructions for browser caching go in the headers of HTTP responses from the hosting server.

5. Minimize the inclusion of external scripts

Any scripted webpage elements that are loaded from somewhere else, such as external commenting systems, CTA buttons, or lead-generation popups, need to be loaded each time a page loads.

6. Don't use redirects, if possible

A redirect is when visitors to one webpage get forwarded to a different page instead. Redirects add a few fractions of a second, or sometimes even whole seconds, to page load time
