Challenge
Veeam components do not have direct internet access, but the customer wants to use restore to Microsoft Azure/Amazon EC2 or object storage (capacity tier) that requires an internet connection. The customer has an HTTP(S) proxy and Veeam components must use it.
Cause
Customer network configuration does not allow direct internet access for Veeam components.
Solution
If you use an HTTP(S) proxy server to access the Internet, make sure that WinHTTP settings are properly configured on Microsoft Windows machines with Veeam backup infrastructure components.
The following command will set the proxy (all protocols) to 192.168.111.111 port 8888:
netsh winhttp set proxy proxy-server="192.168.111.111:8888"
Current WinHTTP proxy settings:
Proxy Server(s) : 192.168.111.111:8888
Bypass List : (none)
It is important not to specify "https".
Run this command for all protocols.
Known Limitation: WinHTTP does not support authentication.
