Installation & Startup

System Service Installation Failed?

Cause	Solution
UAC canceled	Click "Install System Service" again and approve the UAC prompt
Antivirus blocking	Add Rover to your antivirus whitelist
Old version残留	Uninstall first, then reinstall

See System Service.

Core Started But Status Light Doesn't Turn Green?

1. Check if the API address and port are correct (Settings → Basic)
2. Check if the port is in use by another program
3. Check the Logs page for error messages
4. Try changing the Mixed port and restarting

Windows Says "This App Has Been Blocked"?

Click "More info" → "Run anyway". This is a normal Windows SmartScreen prompt for unsigned apps.

Connection Issues

Can't Access the Internet After Enabling System Proxy?

1. Confirm the core is running (status light is green)
2. Try switching to another node
3. Check if system proxy settings were modified by other software
4. Check the Connections page to confirm traffic is going through Rover

TUN Mode Won't Enable?

1. Confirm RoverService is installed (Settings → About)
2. Confirm RoverService is running
3. Check for conflicts with other VPN software
4. Try uninstalling and reinstalling the system service

See System Service.

Some Websites/Apps Can't Be Accessed?

1. Find the connection on the Connections page and check which rule was matched
2. If it matched a direct rule but should go through proxy, add a proxy rule in Policies
3. Enable TUN mode to ensure all traffic goes through Rover
4. Check if DNS policies are correct

Node Issues

All Nodes Show Timeout?

1. Check if your network works normally (can you browse without proxy?)
2. Confirm your subscription hasn't expired
3. Try updating the subscription
4. Check if system time is correct (a difference of more than 90 seconds causes TLS failures)

High Node Latency?

1. Switch to nodes in a different region
2. Check your local network conditions
3. Try TCP nodes instead of UDP
4. During peak hours, routes may be congested

DNS Issues

Some Domestic Websites Don't Load After Enabling Proxy?

1. Check if DNS policies are routing domestic domains to proxy DNS
2. Confirm unmatched domains use direct DNS
3. Check for DNS rule mismatches

Quick Troubleshooting

Search for the inaccessible domain on the Connections page and see which DNS rule it matched. If it matched proxy DNS, change it to direct DNS.

How to Prevent DNS Leaks?

1. Configure dedicated proxy DNS rules for sensitive domains
2. Set unmatched domains to use proxy DNS
3. Use Rover DNS service for concurrent resolution

See DNS Deep Dive and DNS Leak Prevention Scenario.

Configuration Issues

Rules Not Taking Effect After Modification?

1. Rule changes automatically restart the core — wait a few seconds
2. Check if the rule is enabled (toggle on the left)
3. Check rule order — it may be matched by a rule above
4. Confirm which rule traffic actually matches on the Connections page

Rules Disappear After Subscription Update?

• If "Override Rules" is enabled, your custom rules replace the subscription's built-in rules
• If "Override Rules" is disabled, subscription rules are preserved as the base

See Config Generation.
