DocuSign Connect将仅发布到标准/默认端口：

DocuSign Connect will only publish to the "standard/default" ports:

• 在DocuSign演示环境（demo.docusign.net）中Connect将发布到端口80（ http ）或端口443（ https ）。如果URL以 http 开头，则Connect将尝试发布到端口80 。如果URL以 https 开头，则Connect将尝试发布到端口443 。

• In the DocuSign demo environment (demo.docusign.net) DocuSign Connect will publish to either port 80 (http) or port 443 (https). If the URL starts with "http", Connect will attempt to publish to port 80. If the URL starts with "https", Connect will attempt to publish to port 443.

在DocuSign生产环境（www.docusign.net）中，DocuSign Connect仅发布到端口443 （ https ）。在生产环境中 不支持发布到端口80 （ http ）-侦听器端点必须为 https 。

In the DocuSign production environment (www.docusign.net), DocuSign Connect will only publish to port 443 (https). Publishing to port 80 (http) is not supported in the production environment -- the listener endpoint must be https.

因此，建议您从URL中删除端口号为DocuSign Connect配置指定的名称，并确保侦听器端点位于端口80（用于演示）或端口443（用于演示或产品）上。如果那不能解决您的问题，那么您可能需要查看其他论坛帖子的答案： Docusign连接服务未将数据发布到指定的URL 。

Therefore, I'd suggest that you remove the port number from the URL that you've specified for the DocuSign Connect configuration, and ensure that your listener endpoint is located at either port 80 (for demo) or port 443 (for demo or prod). If that doesn't resolve your issues, then you might want to review the Answer for this other forum post: Docusign connect service not posting data to specified url.
