Troubleshooting involves several steps: 1) Verify your TLS certificate is valid and correctly installed on your origin server (if using Full or Full (strict)). 2) Check Cloudflare's SSL/TLS settings in the dashboard. 3) Use an SSL checker tool (like SSL Labs) to analyze the TLS configuration. 4) Review Cloudflare's logs for any errors. 5) Ensure your origin server supports the TLS protocols and cipher suites Cloudflare is using. 6) Temporarily disable Cloudflare's proxy to see if the issue persists directly on your server.
