Is this new? I never saw this before but all of a sudden every pageload is getting a bot check. Even worse, more than half the time it doesn't actually work properly, so the page fails the load and gets stuck with part of the ui loaded and no pages loading until I refresh and then get a bot check. I had to try to load the next chapter of a manga five times before it actually successfully got there instead of failing to load and then going back to the previous chapter after the bot check. Also I had to try multiple times to post this thread because it kept running into an error which I can only assume was another failed bot check attempt.
 
Solution
Summary of where we're at now, with a couple updates from what I've seen on the Discord this morning (US time):

1. You need cookies enabled. The one in use for this specific utility is 'MD-Edge-ID'. If you don't have cookies enabled, expect weirdness. If you clear browser data every time you close the browser, expect to see this every time you start your browser.

2. Each browser on each device needs its copy of the cookie, so if you use two different browsers to get to MD on your desktop and also access MD on your phone, that's three places to see this.

3. Dynamic IP ranges should be reasonably accommodated at this point. No information has been given as to exactly how open these ranges are, but the settings on MD's side were...

I can't read anything anymore well over half the time. It says I pass the challenge and then chapter images insta-fail loading. Tried changing my VPN location, tried closing and reopening the browser, tried hard refresh, and it doesn't fix it. It just decides it wants to work or not depending on its mood. Are there solutions I haven't tried that might work? Probably, but I should not have to jump through hoops to make the site work as a regular user. Whatever you have setup... this ain't it.

Oh, Troubleshoot Mode works! Just have to disable every extension and your VPN to (illegally) read comics on MangaDex.

Yeah. Site is literally unusable now. I genuinely cannot believe I'm being forced back to aggregator slop websites by the very measures being put in place to try to curtail the scrapers those sites use. You can't make this up...

All I had to do was exempt MD from Noscript and that all stopped. The browser console shows them doing some interesting SHA256 stuff, some of which was failing due to an internal hash mismatch on their side and seemed to be related to the manga I was reading, but it didn't affect any ability to read my old favorites and Powblock worked just fine. FWIW I'm on crappy mobile phone hotspot too, so even with CGNAT it was plenty stable.


A VPN will work perfectly provided you don't make it, or let it, change your IP every ten seconds. Some are so paranoid they change IP every request which is insane.

Any idea why my two computers behave completely differently? Both use noscript, ublock, surfshark, and firefox. Both have these configured the exact same way. My laptop has no issues with the site, but my desktop computer can't seem to load anything anymore. The first few times I passed the robot check on my desktop I was able to read fine, but now it's just straight unusable. (and yes, mangadex is on my whitelist for noscript, and no, surfshark is set up to keep my IP the same after it connects, though what it gives me initially is random) I even tried clearing all the cookies for this site in firefox, but it did absolutely nothing.

There have been a couple folks who have run into issues with noscript, even though it's whitelisting mangadex.org - try also whitelisting mangadex.network and see if that has an effect (see here for one user's experience there).

At the risk of sounding like level 1 tech support, have you tried restarting the desktop?

Beyond that, I can only offer that everyone I've been able to help, or that I've seen staff be able to help, successfully has had something on their side that needed changed, and the best way to try and resolve the issue is to be systematic - switch everything you can think of off, and then bring it back in once piece at a time until it stops working, and that's your likely culprit.

Is there no caching of prior ip addresses? I get constant checks on my phone every time I switch from being at home to 'trying to read something on the bus' and then again once I get back home.
