When I go to Shift 8 CDN settings/Purge and try to purge, it says only, “Error Detected : unknown”

I also have a new entry on the Gowalle Guestbook, but it is not displaying. That’s why I wanted to purge the page.

Following is the info that that I was told to copy into my message about the configuration of the site.

Hi, after I enable the shift8cdn on my website, pages with elementor stopped working and also some media doesn’t show anymore on my website.

Those pages with elementor shows an error message that says

There has been a critical error on this website.

This is not specific question related to your service or plugin. But if I’m going to install a CDN service I’ll use your service as I’ve good experience with you in past. So, my question is like if I’m using Cloudflare for my WordPress website do I need to use the CDN service? I think the question is specific and clear.

Yesterday afternoon it was indicated that a customer’s website was taking an exceptionally long time to load. Looking into it, this was the case as it wouldn’t load images and took a massaive amount to load a basic structure or weird listing of links in place of the designed page.
After looking at issues like potential malware and other concerns, I turned off the CDN and the pages started loading again properly. This was the case for (7) pages that I maintain.
After doing this I ran the “test before enabling” link and it returns a blue screen “Error – 504 Gateway Timeout – Webdesign & Development by Shift8”

hi, how can I specify URL in the plugin and also is the cdn automatically enabled for the below files

Enable CDN for CSS files

Enable CDN for JS files

Enable CDN for Media files

I don’t seem to be able to exclude more than one element from the cache.

(.*).mp4

That works but:

(.*).mp4
(.*).pdf

Doesn’t.

I try to exclude the cache folder /wp-content/cache/

I tried /wp-content/cache/(.*) but it seems not to work… there are subfolders in /wp-content/cache/, so should it be /wp-content/cache/*/(.*), or something?

Hello Shift8 CDN Team,

Thanks for making this great WordPress plugin for CDN services.

Recently, I found that some of my sites will occur 502 Bad Gateway ERROR. Following your instructions on https://www.ads-software.com/support/topic/cdn-network-is-working/, I talked to my hosting provider. However, from their end, everything goes fine and works well! That’s very strange.

Then I did a lot of testing and found that the 502 Bad Gateway ERROR only occurs when the user is from Hong Kong. I’ve opened many Virtual Machines (VMs, just simply using Windows Server 2022 and browsing with Edge browser) from Microsoft Azure Cloud, Google Cloud, Amazon AWS Cloud, and Tencent Cloud, simulating user browsing from different places on the earth. For the VM located in the US, Japan, Mainland China, or others, everything worked! However, if the VM is located in Hong Kong, from whatever cloud service provider, it will occur 502 Bad Gateway Error (Just log in to WP-admin for Shift8 CDN Settings: Test URL before enabling : [Click to open test URL in new tab]).

I understand that you have CDN nodes in Hong Kong, but users browsing from Hong Kong will get 502 Bad Gateway errors. That’s so crazy.

I hope that this problem can be fixed soon.

Just a kind reminder: This plugin is not?properly prepared for localization. If you would like to translate this plugin,?please contact the author. Please make the plugin read for translation.

My certficate shows valid when I check from the website security area on chrome but when I try to check in the plugin, it puts up the error, “Error Detected : cURL error 60: SSL certificate problem: certificate has expired”.

Kindly help me in resolving the issue.

Hi I have a paid plan and I’ve submitted two support tickets within 72 hours with no response. My plan allows for 24/7/365 Priority Enterprise Support and yet I have not received support.

Through this free forum, I found one fix but I’m still having issues. According to my Shift8 dashboard, I have not used any Bandwidth in the past 72 hours. Please respond to my support tickets.

The CDN is down!

The Browser cannot open the page https://1sglaqzgxhla.cdn.shift8web.com/wp-includes/js/dist/vendor/wp-polyfill.min.js?ver=3.15.0 because the server is
connection ended unexpectedly. This sometimes occurs when a server is overloaded. Wait a few minutes and then try again.

BANDWIDTH FOR YOUR PERIOD

0 GB / 1000 GB

Yesterday I updated a js file from 4.6 to 5.3. Since this, I have any numbers of time clicked “Clear Cache” on shift CDN dashboard and in the plugin itself, but it is still the old file that is delivered (4.6). Is this a known behavior sometimes? Should I just wait? Should I set up a new layer?

I created my shift8 account and installed the plugin, but it does not sync with the shift8 website, the test link appears ¨if you are seeing this, it is working¨, but when pressing the check button or trying to clear the cache gives error ¨Error detected: unknown¨.
My site has everything working correctly, I have error-free integrations with other platforms, I believe the error is with the shift8 platform, how can I solve this integration error? all data for integration is correct and new domains duly pointed to shift8, it has been possible for months this account believes that if the problem were effective, it would have already propagated. Does the platform really work? or you have restrictions, blockages, etc.
I look forward to your help, thank you very much!

We are using a theme with pixi.js which loads images in a slider, with media from cdn we get the error SecurityError: The operation is insecure, even when we set the url to the files. Is this a cors problem you ever have heard of, of is it an error in the theme and the developer has to make changes?

Hi – there appears to be an SSL issue when fetching items from the CDN. For example:

https://xxxxxxxxxx.cdn.shift8web.ca/wp-includes/css/classic-themes.min.css?ver=1 net::ERR_CERT_DATE_INVALID

Thanks

Hi. The CDN is working? I get error 502 when I go to check for the test. I use wp. Thanks for your help

The ssl cert of shift8cdn.com is expired on 17. August. Please renew.

Hello, first, I want to say thank you for your CDN, it is great!

Unfortunately, images, that are set via that Elementor are not loaded from the CDN, I think it is a problem with Elementor, but maybe you know a workaround?

I’m having trouble fixing a CORS failure.

Shift8 CDN is causing a very slow website, with none of the images, CSS and JS being loaded. What could be wrong?

Hello! So I installed y’all’s plugin and it works perfectly with no issues! I also combined the files using Asset Cleanup and it works nicely. The only thing is, so far there has been no speed increase that I’ve noticed. Is this because
(1) I haven’t waited long enough?
(2) Shift8CDN isn’t the fast CDN that i need?
(3) CDN is just not right for my website?

Thank you!

I run into a CORS problem when loading the ‘/wp-admin/admin-ajax.php’ in the projects section of my website.

I have added the following directive in the htacces, but it still doesn’t work.

I would appreciate any suggestions on how to fix the problem.

<IfModule mod_headers.c>    
    Header set Access-Control-Allow-Origin *
</IfModule>

Thanks in advance

I provide a screenshot

Hi,
I get a good response on the Core Settings page when I click Register, I get a page with a face (If you can see this then it works).

But, when I click on “Check” I get an error message: Error Detected : unknown.

The dashboard says I’ve got 1/2 zones.

Is Shift8 working for me or not?

I’ve got a pic to submit if you want to see it?

It works well!

An error message appears in the CDN panel: Error Detected : cURL error 60: Peer’s Certificate has expired.

If I disable the CDN, it displays it fine. If I enable it, the style sheet is not displayed.

Any suggestions

Thanks

My setup is serverless and any upload will be gone after inactive, just want to check if the CDN still refers to the file from my server? Or everything can be stored and handled on the CDN after my first upload?
