Uncloud Cluster Fix: Use uc ctx conn for Unresponsive SystemsUncloud users experiencing cluster unresponsiveness can use the 'uc ctx conn' command to select a different default machine for proxy traffic. This workaround helps when services are running but new deploys fail, potentially due to WireGuard + Tailscale + IPv6 issues. Users with NAT home networks need to redirect ports 80/443 to the new machine's local IP and redeploy services. Let's Encrypt certificate registration requires machine discoverability.

AI Resource Usage Visibility: CPA Platform Lacks Quota DataUsers integrating AI accounts (e.g., Codex/GPT) into a CPA platform are reporting a lack of visibility into usage statistics and account quotas. While the accounts can be called successfully, the platform does not display critical information needed for cost management and resource planning. Community discussions suggest that usage statistics features might need to be manually enabled or found within specific 'quota management' sections, indicating a potential configuration or user interface challenge for new adopters.
