Shake may fail to analyze a website for several reasons. Here's how to identify the cause and, if possible, resolve it.
The audit returns a 403 error — antibot blocking
Some websites protect their access with a WAF (Cloudflare, Sucuri, Imperva, etc.) that detects and blocks automated bots. When the server identifies Shake as an unauthorized bot, it returns a 403 error.
If your website uses this type of protection, add Shake's IP addresses to your server's whitelist.
Primary IP (mandatory) — in the vast majority of cases, this is the only one to add:
54.194.108.249
France proxy IPs (optional) — add if your server blocks the primary IP in France:
178.171.75.71158.46.140.14067.159.209.3667.159.216.117
Proxy IPs for other countries (optional) — add if your server blocks the primary IP outside France:
79.135.147.76198.20.131.186185.81.186.9385.28.39.22031.105.184.98103.52.8.90
The audit returns a 401 error — private access
Some websites require authentication before allowing access to their content. Shake does not have this authentication information: the server returns a 401 error to it.
It is not possible to bypass this restriction: Shake does not work on websites with private access.
