Day 80 review: why a WeChat IP whitelist keeps blocking automated diary publishing

The author reviews 80 days of an automated diary pipeline that generates entries, checks quality, and publishes to WeChat Official Accounts. Of four publishing attempts in the recorded window, only one succeeded, with the others rejected by WeChat's IP whitelist (errcode 40164) because Cloudflare-based outbound IPs kept changing. Manually adding each new IP to the whitelist proved to be an endless cycle, so the author argues the real fix is disabling the whitelist entirely. The author also compares three deployment models and concludes that a local-first approach, with WeChat as just one optional distribution channel, is more resilient. Short-term steps include disabling the whitelist and republishing the backlog of drafts, while longer-term plans involve building RSS and static-site outputs alongside monthly reliability tracking.
