换个域名看看，你80 443 有没有被占用？

换个域名看看，你80 443 有没有被占用？

之前被占用了，系统自带Apache2，我卸载后那个没再提醒占用。如果占用的话你的脚本会有提示的

那我换个别的域名看看

root@le:~# Job for caddy.service failed because a timeout was exceeded.
See "systemctl status caddy.service" and "journalctl -xe" for details.

我看到这个提示了，不知道该怎么解决，请指点思路，看来不是域名的问题，因为域名用别的服务器没问题

Job for caddy.service failed because a timeout was exceeded.
See "systemctl status caddy.service" and "journalctl -xe" for details.

我问了一下ai，ai说是证书没签下来

Possible Causes of Timeout:

There are several reasons why the connection to Let's Encrypt might be timing out:

Network Issues:
Your server's internet connection might be unstable or slow.
There could be temporary network congestion between your server and Let's Encrypt.
Firewall Restrictions:
A firewall might be blocking outgoing connections to Let's Encrypt's servers.
DNS Issues:
The DNS records for your domain (chushen.fu.bi) might not be properly configured or propagated.
Troubleshooting Steps:

Check Network Connectivity:
Verify your server has a stable internet connection.
Run a speed test or try pinging acme-v02.api.letsencrypt.org to check latency.
Review Firewall Rules:
Ensure your firewall allows outbound connections to port 443 of acme-v02.api.letsencrypt.org.
Verify DNS Configuration:
Make sure your domain name points to the correct server IP address and the DNS records have propagated globally.
You can use online tools like dig or nslookup to verify propagation.
Additional Tips:

Consider increasing the timeout value in your Caddy configuration (if supported) to provide more time for the connection.
Check the Let's Encrypt status page (https://letsencrypt.org/stats/) for any known outages.
By following these steps and checking the potential causes, you should be able to resolve the timeout issue and allow Caddy to obtain a valid SSL certificate for your domain.

然后在caddy的日志里面发现了no IPv4 addresses to try as fallback，是不是因为这个原因没有ssl证书的？
