You open your browser, type in the usual address of CrunchyScans, and the page remains blank. No clear error message, no redirection, just a screen that won’t load. This scenario is affecting more and more French-speaking manga and webtoon readers. The problem doesn’t always come from the site itself: several technical mechanisms, often invisible, prevent the connection from succeeding.
SNI Filtering and DNS Blocking: What Really Cuts Access to CrunchyScans
Most online guides suggest changing your DNS to bypass a block. This advice worked well a few years ago, but French ISPs are now combining several blocking techniques.

A classic DNS block involves preventing the resolution of the domain name. Specifically, when you type an address into your browser, your internet service provider pretends not to know this site. Changing your DNS (for example, to Google’s or Cloudflare’s) was enough to regain access.
Since 2024, ISPs have added IP filtering and SNI filtering to DNS blocking. SNI (Server Name Indication) is information sent by your browser to the server at the very beginning of the connection. It indicates which site you want to visit. The ISP can read this information and cut the connection even before the page starts to load.

If you’ve already checked the causes on Rennes Blog, you will find this distinction between simple blocking and enhanced blocking.
With this triple lock, simply changing your DNS is no longer enough. This is the main reason why CrunchyScans seems completely inaccessible to some readers, while others can access it without issue from another country or network.
CrunchyScans Domain Changes: Why the Address No Longer Works
ARCOM (the authority that regulates online content in France) regularly orders the blocking of domain names linked to unauthorized reading sites. In 2025, thousands of additional blocks were issued, significantly increasing the number of sites inaccessible via French ISPs.
In response to these decisions, CrunchyScans has changed its address several times. The old .fr domain no longer points to anything active, and the new addresses are mainly circulating on Discord or in private groups.
The address you have bookmarked is probably outdated. This is a common trap: the site still exists under another URL, but you keep loading the old one, which is now blocked or abandoned. Before thinking about a technical problem on your end, first check if the address itself has changed by consulting the official account on the site’s social media.
Ad Blockers and Browser Extensions That Prevent Loading
CrunchyScans, like many free scan sites, relies on advertising to function. Some ad blockers do not just hide banners: they also block scripts necessary for loading reading pages.
You may have noticed that the homepage loads, but the chapters remain empty or display an error. This behavior is typical of a conflict with a blocker. Here are the checks to perform:
- Temporarily disable your ad blocker (uBlock Origin, AdGuard, or the one built into your browser) for the site only, then reload the page.
- Check that you do not have a VPN or privacy extension that modifies network requests, such as Privacy Badger or Decentraleyes, as they can interfere with image servers.
- Test the site in a private browsing window without active extensions: if the page works in this mode, the problem comes from one of your extensions.
This diagnosis takes less than a minute and eliminates the most common cause of user-side malfunction.
Concrete Solutions When CrunchyScans Remains Inaccessible
If changing DNS alone is no longer enough due to SNI filtering, what options remain? Here are the approaches that actually work in 2025.
Use a VPN to Bypass Network Blocking
A VPN encrypts all your traffic and routes it through a server located in another country. The ISP can no longer see the requested DNS, the SNI, or the destination IP address. This is the only reliable method against a triple DNS, IP, and SNI block.
Choose a VPN that does not slow down the connection too much for image reading. Free versions often impose bandwidth limits that make loading scans tedious.
Configure an Encrypted DNS (DoH or DoT)
DNS-over-HTTPS (DoH) encrypts your DNS requests so that the ISP cannot read them. This option is built into Firefox and Chrome:
- In Firefox, go to Settings, then Privacy & Security, and enable “DNS-over-HTTPS” with Cloudflare or NextDNS as the provider.
- In Chrome, go to Settings, then Privacy and Security, and enable “Use a secure DNS” with your chosen provider.
- On Android, the system setting “Private DNS” allows you to enable DoT (DNS-over-TLS) for all applications, not just the browser.
Encrypted DNS resolves DNS blocking, but does not bypass SNI filtering. If the site remains inaccessible after this configuration, it means the ISP is also using SNI filtering, and only a VPN will work.
Clear Local DNS Cache
Your computer keeps a record of recent DNS resolutions. If CrunchyScans has changed its IP address or domain, your system may still point to the old destination. On Windows, open the command prompt and type ipconfig /flushdns. On macOS, the equivalent command goes through the Terminal. This cleaning forces your machine to re-request the address from the DNS server, which can be enough when the site has just migrated.
Security and Intrusive Ads on Scan Sites
Even when CrunchyScans is working, browsing is not without risk. Free scan sites regularly display aggressive ads: redirects to misleading pages, pop-ups mimicking system alerts, or automatic downloads of suspicious files.
Completely disabling your blocker to access content exposes you to these nuisances. There is a compromise: configure your blocker to allow only scripts from the main CrunchyScans domain while filtering out third-party ad domains. This approach requires manual adjustment but preserves both access to chapters and minimal protection against malicious content.
The choice between reading comfort and browser security remains a constraint specific to this type of platform. Keeping your system and browser up to date reduces the attack surface, even without an active blocker.
