Azure站点到站点VPN的间歇性RDP问题
我们已经开始使用Azure，并在Azure Iaas中为O365引入了一个Veeam备份服务器。现在使用它2周，并开始从我们的内部部署网络看到间歇性的RDP连接问题，并给出"内部错误"。消息。
We have started using Azure and introduced one Veeam backup server for O365 in Azure Iaas. Using it for 2 weeks now and started seeing intermittent RDP connection issues from our on-premise network and gives "Internal Error" message.
在行为期间无法ping / psping但是在此期间站点到站点连接已启动并已连接。
Unable to ping/psping during the behavior however site to site connection is up and connected during this time.
重新启动服务器会解决暂时发布。
Restarting the server resolves the issue temporarily.
感谢有人可以帮助进一步建议可能存在问题的区域，以便永久修复它。
Appreciate if someone can help further to suggest what could be the problem area to fix it permanently.
谢谢，

这可能是服务器本身，S2S VPN或On-Prem的问题。
This could be an issue with the server itself, the S2S VPN, or an issue from On-Prem.
第一步是缩小问题的来源。最简单的方法是查看是否可以连接到同一VNET中的其他服务器，或者查看是否可以在发生这种情况时连接到备份服务器的公共IP。
The first step is to narrow down where the issue is coming from. The easiest way to do that is to see if you can connect to a different server in the same VNET, or see if you can connect to backup server's public IP while this is happening.
如果您能够从公共IP而不是VPN访问您的VM，则VPN存在问题。如果您无法通过任何一种方法访问服务器，则可能是服务器出现问题。
If you are able to reach your VM from the public IP but not the VPN, it is an issue with the VPN. If you are not able to reach the server via either method, it is likely an issue with the server.
