无法连接到主机C：主机名未找到（11001）Windows，DNS问题？ [英] Cannot connect to host in C: Hostname not found (11001) on Windows, DNS Problem?
问题描述
我正在尝试使用连接到C中的远程服务器的API，但我仍然收到以下错误消息：
I am trying to use an API that connects to a remote server in C, but I keep having the following error message:
log_message: 15:13:19.489 I [ap:1388] Connecting to AP A3.spotify.com:4070
log_message: 15:13:19.490 E [ap:1324] AP Socket Error: Hostname not found (11001)
log_message: 15:13:19.491 E [ap:3396] Connection error: 4
log_message: 15:13:19.491 I [ap:1388] Connecting to AP A1.spotify.com:80
如您所见，日期，错误消息是即时的，所以我认为某些东西在我的电脑上本地阻止了消息。
As you can see with the dates, the error message is instantaneous, so I think something is blocking the messages locally on my computer.
这是使用Wireshark捕获的TCP流：
Here is the TCP stream I captured with Wireshark:
30 1.682802 MyLocalIp 193.182.8.15 HTTP Continuation or non-HTTP traffic
31 1.702236 193.182.8.15 MyLocalIp HTTP Continuation or non-HTTP traffic
33 1.901706 MyLocalIp 193.182.8.15 TCP 50222 > http [ACK] Seq=12 Ack=12 Win=251 Len=0
所以，根据Wireshark ，我的电脑发送的第一封邮件头标题不正确。
So, according to Wireshark, the first message sent by my computer has an incorrect Header checksum.
我知道主机是正确的，因为当我在Java中使用与JNA相同的C API时，具有以下结果：
I know the host is correct, because when I use the same C API in Java with JNA, I have the following result:
log_message() called:15:46:48.718 I [ap:1388] Connecting to AP A1.spotify.com:4070
log_message() called:15:46:53.769 E [ap:1324] AP Socket Error: Undefined Error 0x4E20 (20000)
log_message() called:15:46:53.770 E [ap:3396] Connection error: 117
log_message() called:15:46:53.770 I [ap:1388] Connecting to AP A2.spotify.com:80
log_message() called:15:46:53.789 I [ap:938] Connected to AP: 193.182.8.12:80
所以，这里4070端口的连接失败，这是正常的，因为它被公司的防火墙阻止，然后在端口80上成功。
So, here the connection fails on port 4070, which is normal because it is blocked by the company's firewall, and then it succeeds on port 80.
这里是Wireshark ca Java版本：
And here is the Wireshark capture for the Java version:

133 7.721265 193.182.8.15 MyLocalIp HTTP Continuation or non-HTTP traffic
我尝试在我的System32 / drivers / etc / hosts中添加IP 193.182.8.15文件为主机名A1.spotify.com，A2.spotify.com和A3.spotify.com，但它没有改变任何东西。
I tried adding the IP 193.182.8.15 in my System32/drivers/etc/hosts file for the hostname A1.spotify.com, A2.spotify.com and A3.spotify.com, but it didnt change anything.
我关闭Windows防火墙和防毒软件也没有帮助。
I shut down the Windows firewall and antivirus, it didn't help either.
我尝试在家里运行这个没有公司代理和防火墙的东西，但是它是一样的（除了Java版本的服务可以连接4070端口）
I tried running this at home without company proxy and firewall, but it was the same (except that on the Java version the service was able to connect on port 4070)
任何想法？
谢谢！
