If you're encountering "LOLMiner DNS over HTTPS resolve failed" errors, you're not alone. This issue often stems from misconfigurations in your network settings, problems with your DoH provider, or underlying network connectivity issues. This guide provides a systematic approach to diagnose and resolve this problem.
DNS over HTTPS (DoH) encrypts your DNS queries, enhancing your privacy by preventing eavesdropping on your internet activity. LOLMiner, a cryptocurrency mining software, relies on a functioning DNS to access mining pools and update its configuration. When DoH fails, LOLMiner cannot connect properly.
Ensure you have a stable internet connection. Try accessing other websites to rule out broader connectivity problems.
Examine LOLMiner's configuration file (usually a `.bat` or `.conf` file depending on your OS) and verify the DoH server address is correctly specified. Common DoH providers include Cloudflare (https://cloudflare-dns.com/dns-query) and Google Public DNS (https://dns.google/dns-query). If you're unsure what to use, try a different provider. Ensure the address is accurate and accessible.
Use a command-line tool like `curl` or `wget` (on Linux/macOS) to test the DoH server's responsiveness. For example, using `curl`:
curl -X POST -H "Content-Type: application/dns-message" --data ""
https://cloudflare-dns.com/dns-query (For testing purposes only!) Temporarily disable your firewall and antivirus software to see if they are blocking DoH traffic. If LOLMiner works correctly after disabling them, configure your security software to allow DoH traffic.
Ensure your router isn't blocking or interfering with DoH traffic. Consult your router's documentation for instructions on managing DNS settings and firewall rules.
Make sure you're using the latest version of LOLMiner. Older versions may contain bugs that cause DoH failures. Check the official LOLMiner website or repository for updates.
If your system's default DNS resolver is having problems, you can try configuring LOLMiner to use a different resolver by temporarily overriding system DNS settings (though this is usually not recommended). Note that setting this may impact other applications on your system
LOLMiner usually generates log files. Examine these logs for more specific error messages that might provide clues about the cause of the DoH failure.
If the above steps don't resolve the issue, you might need to consider more advanced troubleshooting techniques, such as:
Remember to always back up your configuration files before making any changes. If you're unsure about any step, it's best to seek assistance from someone with experience in networking and system administration.
