Raspberry Pi - Security and DeploymentYou configured HTTPS on Raspberry Pi but browsers show a 'certificate not trusted' warning. What should you check first?AIf the web server is running on port 80BIf the Raspberry Pi has enough RAMCIf the SSL certificate is self-signed instead of from a trusted authorityDIf the domain name is spelled correctly in the URLCheck Answer
Step-by-Step SolutionSolution:Step 1: Understand certificate trust warningsBrowsers warn if the certificate is self-signed or not from a trusted authority.Step 2: Evaluate other optionsRAM, port, or domain spelling do not cause trust warnings directly.Final Answer:If the SSL certificate is self-signed instead of from a trusted authority -> Option CQuick Check:Trust warning = Self-signed cert issue [OK]Quick Trick: Use trusted CA certificates to avoid browser warnings [OK]Common Mistakes:MISTAKESIgnoring certificate authorityChecking unrelated hardware issuesAssuming port or spelling causes trust errors
