https证书申请报错"Can not init api"

[yangli-learning]

安装脚本trojan_install.sh时出现：

0 0 * * * "/root/.acme.sh"/acme.sh --cron --home "/root/.acme.sh" > /dev/null
[Thu Jan 19 04:26:19 EST 2023] Good, bash is found, so change the shebang to use bash as preferred.
[Thu Jan 19 04:26:22 EST 2023] OK
[Thu Jan 19 04:26:22 EST 2023] Install success!
[Thu Jan 19 04:26:33 EST 2023] Please refer to https://curl.haxx.se/libcurl/c/libcurl-errors.html for error code: 60
[Thu Jan 19 04:26:33 EST 2023] Can not init api for: https://acme-v02.api.letsencrypt.org/directory.
[Thu Jan 19 04:26:33 EST 2023] Sleep 10 and retry.

该错误重复大约十次左右。最后显示https证书申请失败。

===================================
https证书没有申请成果，自动安装失败
不要担心，你可以手动修复证书申请
1. 重启VPS
2. 重新执行脚本，使用修复证书功能
===================================

通过ping测试注册的域名解析并没有问题。尝试重装或修复证书都会出现该错误。不知是否有人遇到过这个问题？

P.S curl.haxx.se/libcurl/c/libcurl-errors.html 的错误60是：

CURLE_PEER_FAILED_VERIFICATION (60)
The remote server's SSL certificate or SSH fingerprint was deemed not OK. This error code has been unified with CURLE_SSL_CACERT since 7.62.0. Its previous value was 51.

安装环境为CentOS7.
