AI tool 'not found' errors traced to intermittent DDNS failures

By PulseAugur Editorial · [1 sources] ·

A user encountered intermittent issues where AI models like Claude and ChatGPT reported tools as "not found" or "invisible" during sessions. These probabilistic failures, which would typically be resolved by a human retrying, became apparent when AI models relied on consistent tool availability. The root cause was identified as a dynamic DNS (DDNS) service, specifically dynv6.net, intermittently failing to resolve the server's hostname. The user plans to implement Cloudflare Tunnel to establish a persistent outbound connection, bypassing the need for DDNS and port forwarding. AI
