upload:r2:full failed with ETIMEDOUT to Cloudflare R2 IPs; root cause is local network reachability, not S3 credentials.

Date: 2026-08-29 11:00 Summary: upload:r2:full failed with ETIMEDOUT to Cloudflare R2 IPs; root cause is local network reachability, not S3 credentials.

[question] @terminals/1.txt (npm run upload:r2:full AggregateError ETIMEDOUT to 172.64.190.1:443 / 172.64.66.1:443)

[try to solve]

Log showed transport=s3 and files=1760, so .env R2 S3 credentials were loaded; failure happened on TCP connect to Cloudflare Anycast before PutObject.
Same machine: direct curl to https://cloudflare.com:443 also times out; Cursor-injected HTTP(S)_PROXY=127.0.0.1:55070 was not listening.
Fix: enable a working system/TUN proxy (or VPN) so Node can reach *.r2.cloudflarestorage.com, then re-run npm run upload:r2 (prefer incremental) or upload:r2:full.
Note: scripts/lib/r2-s3-client.mjs does not wire HTTPS_PROXY/ALL_PROXY; HTTP-proxy-only setups still direct-connect to CF IPs unless TUN is used or proxy support is added to the S3 client.

[actions]

Diagnosed via terminal log + local curl/proxy port checks; no code change
