Connection Issues

Client Cannot Connect to Server

Symptom	Possible Causes	Diagnostic Steps	Solutions
"Failed to connect to server"	Wrong IP/port, server offline, firewall blocking	Ping server IP, telnet server port, check server status	Verify IP:port, ensure server running, configure firewall
"Server is full"	Max slots reached, reserved slots active	Check current users, review slot limits	Increase slots, manage reserved slots, wait for space
"Banned from server"	IP ban, hardware ban, false positive	Check ban list, review security logs	Remove ban, appeal to admin, check for false positives
"Invalid password"	Wrong password, password changed	Verify password, check for spaces/caps	Reset password, clear cached credentials
"Connection timeout"	Network issues, server overload, DDoS	Test connection from different network	Check network stability, upgrade bandwidth, DDoS protection

Server Not Starting or Crashing

Error Message	Likely Cause	Diagnostic Command	Fix
"Port already in use"	Another service using port	netstat -ano | find ":9987"	Change port, stop conflicting service
"Insufficient permissions"	Running as wrong user, file permissions	Check user permissions, file ownership	Run as correct user, fix permissions
"Database error"	Corrupted database, disk full	Check disk space, database integrity	Repair database, free disk space
"Memory allocation failed"	Insufficient RAM, memory leak	Monitor memory usage, check limits	Increase RAM, fix memory leak, restart
"Invalid license"	Expired or invalid license key	Verify license status, check expiration	Renew license, contact TeamSpeak support

Audio Issues

Common Audio Problems

Audio Configuration Troubleshooting

# TeamSpeak audio test commands
.testvoice  # Test voice connection
.testcapture  # Test microphone capture
.testplayback  # Test audio playback

# Audio configuration checklist
1. Input Device: Correct microphone selected
2. Output Device: Correct speakers/headphones selected
3. Volume Levels: Input and output balanced
4. Codec: Appropriate for network conditions
5. Voice Activation: Proper sensitivity setting
6. Echo Cancellation: Enabled if needed
7. Noise Reduction: Enabled for noisy environments

# Common audio fixes
- Enable/disable exclusive mode in Windows sound settings
- Update audio drivers to latest version
- Disable audio enhancements in Windows
- Test with different USB port for USB headsets
- Check for conflicting audio applications

Permission and Security Issues

Permission Problems

Symptom	Possible Cause	Diagnostic Command	Solution
Cannot join channel	Channel password, permissions, bans	whoami, permfind	Check permissions, verify password, review bans
Cannot speak	Talk power insufficient, muted	clientinfo, permoverview	Adjust talk power, check mute status
Cannot create channel	Insufficient privileges	permfind i_channel_create_modify	Grant channel creation privileges
Cannot kick/ban	Missing admin privileges	permfind i_client_kick	Grant kick/ban privileges
Cannot modify server	Not server admin	permfind b_virtualserver_modify	Grant server modification privileges

Security Configuration Issues

# Security diagnostic commands
tokenlist  # List active tokens
banlist  # List active bans
complaintlist  # List user complaints
permissionlist  # List all permissions

# Common security issues and fixes
1. Token not working: Regenerate token, check expiration
2. False positive bans: Review ban reasons, adjust auto-ban settings
3. Permission inheritance: Check group inheritance chains
4. Privilege escalation: Review permission assignments
5. Security breaches: Change server admin password, review logs

# Security best practices
- Regular permission audits
- Principle of least privilege
- Strong password policies
- Regular backup of permission system
- Monitoring of admin actions
