"Can't connect", "keeps dropping", "slow speed"—the three most common accelerator complaints. Most can be fixed without technical background. This guide organizes six common issues into a table.
Before switching products, work through "local network → client version → node → firewall" in order. This covers over 90% of failures, starting from the most likely and easiest causes.
XuanFeng's support team analyzed a year of tickets and identified six common connection issues.
| Symptom | Common Cause | Fix |
|---|---|---|
| Cannot connect | No network / old version | Check network, update |
| Frequent drops | Congested node / fluctuation | Switch node |
| Noticeably slow | High node load | Pick lower-load node |
| Node unavailable | Temporary maintenance | Switch to backup |
| Connection blocked | Firewall/antivirus | Whitelist |
| IPv6 anomaly | Compatibility | Upgrade to V3.2 |
If the steps above don't resolve the issue, contact support with the client error code—it helps support quickly identify the issue type.
| Approach | When |
|---|---|
| Self-troubleshoot | Network, version, node, firewall |
| Contact support | Persistent failure, unknown code |
