See my answer below - Avoid using words like "advert" or "advertise" in your scripts, as Adblocking software assume its use and block it from browsers! Not good if you are the programmer wanting your full page content to be shown. — Martin Sansone - MiOEE, May 20 '14 at 14:36

These errors are usually generated from an ad blocking plugin, such as Adblock Plus. To test this use either a different browser or uninstall the ad blocking plugin (right clicking the extension by the URL bar and clicking "Remove from Chrome...").

There is an easier way to temporarily disable an extension. In Chrome, opening an Incognito tab will usually stop extensions running (unless you have specifically told Chrome which ones to run in Incognito).

On a page I had created locally, adblock was still interfering, disabled it for localhost from now on. – Sam Jun 10 '14 at 09:56
I was getting this issue for several sites, and I resolved it by changing my Privacy Badger extension's settings for the sites in question. – Aaron Jul 07 '14 at 01:36

Windscribe also blocks resources – joseantgv Jan 21 '20 at 12:25
I was using Pluckeye Extension and it was doing the same. – Anshuman Kumar Jun 26 '20 at 13:21

In my case I was getting this error because I was using Brave browser that does have a native ad blocker so I just switch to Firefox to run the tests and it was all ok – Jack Nov 05 '22 at 01:12
Brave will naturally do this! You will have to disable its "Brave Shield" for your specific site. – klewis Nov 07 '22 at 15:58

My advice is to avoid any image names; class names or ID's with the words:

Advert
Advertise

in their name!

I ran some tests and Ad blockers regularly block any direct content with these names either within the CSS file, Div or Span Layers.

So an image name loaded via CSS such as advertise-with-us.png gets blocked on any machine running such software for example.

EDIT: I've Traced a list of web page elements in Chrome which AdBlock Plus sets the CSS value to "display:none". They probably apply to other browsers too:

::content #ads > .dose > .dosesingle, 
::content #content > #center > .dose > .dosesingle,
::content #content > #right > .dose > .dosesingle, 
::content #header + #content > #left > #rlblock_left, 
::content .trc_rbox_border_elm .syndicatedItem, 
::content .trc_rbox_div .syndicatedItem, 
::content div[id^="mainads"], ::content #ad-banner-980, 
::content #adbox300600, ::content #chartAdWrap, 
::content #in-content-ad, ::content #main-right-ad-tray, 
::content #second-right-ad-tray, ::content #sponsored-message, 
::content #tr-adv-banner, ::content #votvAds_inner, 
::content #welcome_ad, ::content #wp_ad_marker, 
::content .PremiumObitAdBar, ::content .ad-active

this must be it. I'm developing a rails app with a advert controller. it generates an empty adverts.js.coffee and adblock plus is blocking it, even though it is empty. – Vigrond May 20 '14 at 11:30
Yep! I'd expect it would be blocked. Glad that I could help :) - Annoying as it is, as a rudimentary Adblock script would 'assume' with the word "advert" in it that its showing unwanted ads !!! Programmers tasked with including external ad scripting are just going to use arbitrary id names to get around the current Ad blockers. – Martin Sansone - MiOEE May 20 '14 at 14:30

``banners`` in the URL of a Ajax call is also blocked by AdBlock Plus. – Alexandre R. Janini Jul 29 '14 at 15:48
Ad-Gallery ! Anybody using Ad-Gallery slider will also find assets which genuinely use element names starting "ad-" will also go astray on web pages with AdBlock Plus enabled. Prev & Next buttons as well as active thumb image will all disappear !! - Change the element names within the jquery.ad-gallery.js file to avoid this. – Martin Sansone - MiOEE Oct 09 '14 at 06:31
I would advise not to use advertisements. – Mulan May 18 '16 at 03:47

There are two steps here: troubleshooting and then fixing the issue:

To troubleshoot, check to see if it is a browser and/or extension problem. Chrome, Firefox and others have incognito or private mode which does not load extensions or the basic database of passwords and cookies.
In the case of ERR_BLOCKED_BY_CLIENT that is usually some kind of blocking software, such as Adblock, Ghostery, or some other kind of privacy/anti-spyware tool.

Don't use keyworks like "ad", "ads", "advertise", etc. in image url or image class. Adblock block them automatically.

If you are running multiple extensions that perform ad or script blocking you will need to

individually update each one to your whitelist

Taking from this source, here are some of the extensions that may cause the case and how to deal with them.

Adblock Plus

Click the Adblock Plus icon.
Click “Enabled on this site” to disable ad blocking for the current site.
In Firefox Click “disable on wired.com” to disable ad blocking.
Reload the page you were viewing.
If problem still persist, cek if the character string "-300x600" is in the file name, that particular text pattern matches an expression list pattern in the AdBlock Plus.

Firefox Tracking Protection

In Firefox “Tracking Protection” may activate our adblock notice. It can be temporarily disabled for a browsing session by clicking the “shield” icon in the url bar if visible and following the instructions.
For further details on Tracking Protection please review Mozilla’s support.

Adblock

Click the Ad Block icon.
Click “Don’t run on pages on this domain”.
Reload the page you were viewing.

Ghostery

Click the Ghostery icon.
In Ghostery versions < 6.0 Click “Whitelist site”.
In Ghostery version 7.0 click “trust site”
In Versions < 6.0 You will see the message “Site is whitelisted”. Click “reload the page to see your changes.”
Reload the page you were viewing.

uBlock / uBlock Origin

Click the uBlock / uBlock Origin icon.
Click the “power” button in the menu that appears to whitelist the current web site.
Click the reload icon to reload the page you were viewing.

Disconnect

Click the Disconnect icon.
Click “Whitelist site”.

Kaspersky Ant-Banner
Please review How to configure Anti-Banner in Kaspersky Total Security for information on how to whitelist with Kaspersky Total Security.

As other people have mentioned, this issue is common when using adblock or similar extensions.

The source of my issues was my Privacy Badger extension.

I noticed the same error as soon as I added Google Analytics and started testing on localhost.

I have both AdBlock as well as Ghostery... it actually (for me) wasn't AdBlock interfering - it was Ghostery. To "fix", in Ghostery settings, under "Analytics", uncheck Google Analytics.

You can also just run chrome in incognito mode, that automatically switches off all your plugins/extensions, including any add blockers. Then you can quickly see if the extensions are causing the problem.

I had a similar issue, also seeing "Failed to load resource: net::ERR_CONTENT_DECODING_FAILED" and "ILLEGAL TOKEN" errors when loading JS files locally. Pressing CTRL+SHIFT+DEL and deleting all "Cookies and other site and plugin data" and "Cached images and files" fixed it.

As others have pointed out, you need to disable extensions and retry the page to see if errors reoccur. If not, then the culprit might be one (or more) of them.

On my own case it was a deprecated switch, I've set up long ago. I used process-per-tab which was getting phased-out in recent (48-53) versions. Once I removed that switch all started to work correctly.

A little bit late to the party... but I found this as a solution for me when having "blocked"-Error in chrome:

Blocking resources whose URLs contain both \n and < characters.
