. Check Permissions for socat: The error Permission denied suggests that the acme.sh script is being run by a user without the necessary permissions to bind to port 80. To allow the script to bind to port 80, you have two options:
Option 1: Run as Root
You can run the acme.sh script as the root user, which has the necessary permissions to bind to privileged ports. Caution: Running processes as root can pose security risks, so only do this if you understand the potential implications. Option 2: Use a Higher Port for Standalone Mode
If you prefer not to run as root, you can configure acme.sh to use a higher port (e.g., port 8080) instead of port 80 for the HTTP challenge: bash γ³γΌγγγ³γγΌγγ export LE_HTTP_PORT=8080 ./acme.sh --issue -d munetaka.me --standalone After that, ensure that port 8080 is open and accessible.
If you're using Nginx, for example, you can use the following:
bash γ³γΌγγγ³γγΌγγ ./acme.sh --issue -d munetaka.me --webroot /path/to/your/nginx/webroot This will use the Nginx server's webroot to serve the challenge files.
bash γ³γΌγγγ³γγΌγγ cat /home/acmeuser/.acme.sh/acme.sh.log This might provide additional clues about what went wrong.
Conclusion: The error you're encountering is most likely due to port 80 being unavailable or the permissions required to bind to that port being insufficient. Either ensure that port 80 is free and accessible, or configure the script to use a different port or a running web server.
