sing-box Common Issues

🚫 Cannot access foreign websites but can access domestic websites?

🟡 Situation 1: Just started

When sing-box just starts, before processing foreign domain name resolution, it will first conduct a URL speed test on all available nodes to select the fastest node to complete subsequent DNS resolution. Therefore, before the speed test is completed, you may temporarily be unable to access foreign websites.

✅ Solution: If you don't want to wait for the speed test process, you can manually select an available node, so you can immediately access foreign websites.

🟡 Situation 2: Same problem occurs during use

If you also suddenly cannot access foreign websites during use, it's likely that the currently selected node is unavailable or has poor connection quality.

✅ Solution: Please check the connectivity of the current node, and manually switch to a stable available node when necessary to restore access.


💡 Note: This problem will not affect access to domestic websites, nor will it affect the use of services based on foreign IP (such as Telegram), only affecting access to foreign domain name websites.

⚠️ Report "Service Error", cannot start service

If you encounter the error shown in the image below when starting:

(packet-tunnel) error: start service: initialize rule-set[2]: initial rule-set: geosite-geolocation-cn: Get "https://raw.githubusercontent.com/SagerNet/sing-geosite/rule-set/geosite-geolocation-cn.srs": context deadline exceeded | initialize rule-set[2]: initial rule-set: geoip-cn: Get "https://raw.githubusercontent.com/SagerNet/sing-geoip/rule-set/geoip-cn.srs": initialize rule-set[2]: initial rule-set: geosite-geolocation-cn: Get "https://raw.githubusercontent.com/SagerNet/sing-geosite/rule-set/geosite-geolocation-cn.srs": context deadline exceeded | initialize rule-set[2]: initial rule-set: geosite-geolocation-!cn: Get "https://raw.githubusercontent.com/SagerNet/sing-geosite/rule-set/geosite-geolocation-!cn.srs": initialize rule-set[2]: initial rule-set: geosite-geolocation-cn: Get "https://raw.githubusercontent.com/SagerNet/sing-geosite/rule-set/geosite-geolocation-cn.srs": context deadline exceeded

🟡 Problem cause: This is because your network environment cannot access GitHub, causing the rule files to fail to load.

Solution: Please try switching networks, such as:

  • Switch to other Wi-Fi
  • Switch to mobile network (such as 4G/5G)
  • Change network operator (such as from China Telecom to China Unicom, ask friends for hotspot)

💡 Note: Once the rule files are successfully loaded once, this error will not appear again.
