To troubleshoot Tencent Cloud's IPv6 solution, follow these steps:
1. Check IPv6 Configuration
- Ensure that the IPv6 address is correctly assigned to your instance or service.
- Verify that the IPv6 address is enabled in the network interface settings.
Example: Log in to the Tencent Cloud console, navigate to the instance details, and confirm that the IPv6 address is listed and active.
2. Verify Network Connectivity
- Use tools like
ping6 or traceroute6 to test connectivity to other IPv6 addresses.
- Check if the instance can reach external IPv6 addresses and vice versa.
Example: Open a terminal on your instance and run ping6 google.com to check if IPv6 connectivity is working.
3. Inspect Security Group Rules
- Ensure that the security group associated with your instance allows inbound and outbound IPv6 traffic.
- Verify that the rules are correctly configured to permit the necessary ports and protocols.
Example: In the Tencent Cloud console, review the security group rules for your instance and ensure that IPv6 traffic is allowed on required ports (e.g., port 80 for HTTP).
4. Check Route Table Configuration
- Confirm that the route table associated with your VPC includes routes for IPv6 traffic.
- Ensure that the routes are correctly pointing to the appropriate next hop.
Example: In the Tencent Cloud console, navigate to the VPC route table settings and verify that IPv6 routes are present and correctly configured.
5. Review DNS Settings
- Ensure that your domain's DNS records include AAAA records for IPv6 addresses.
- Verify that the DNS resolver used by your instance can resolve IPv6 addresses.
Example: Use a DNS lookup tool to check if your domain has an AAAA record pointing to the correct IPv6 address.
6. Monitor Logs and Metrics
- Check system logs and network metrics for any errors or anomalies related to IPv6.
- Use Tencent Cloud's monitoring services to track network performance and identify potential issues.
Example: In the Tencent Cloud console, access the Cloud Monitor service to view logs and metrics for your instance and network.
7. Utilize Tencent Cloud Support
- If the issue persists, consider reaching out to Tencent Cloud support for assistance.
- Provide detailed information about the problem, including error messages, configuration details, and steps already taken.
Example: Visit the Tencent Cloud support page and submit a ticket with the necessary details to get expert help.
