What did you do?

When I use the "golang.org/x/crypto/acme/autocert" package in go and call http.Serve (autocert.NewListener("www.hilive.com.tw"), r) to use https for our domain Credentials, when I use this syntax and then centos to enable the service, it happens continuously" 2020/10/23 09:17:10 http: TLS handshake error from 117.135.87.191:5481: acme/autocert: HostWhitelist is not configured "tw .trojan.scloudlab.xyz". Such an error, where did the problem occur?

What did you expect to see?

"Http: TLS handshake error from 58.247.22.169:14692: acme/autocert: host "tw.trojan.scloudlab.xyz" not configured in HostWhitelist" error will no longer appear
