The server rejects bots your robots.txt allows
robots.txt allows these bots, but when we contacted the server using their name, it answered with an error (429). The block is at the hosting, firewall or CDN level, not in robots.txt. Note: some protections also check the IP address, so they may let the real bot in and reject only us. Only ongoing monitoring gives certainty.
Affects: ClaudeBot
How to fix: Check your firewall, mod_security or hosting rules that block by user agent.
