我在 Google Cloud 上，我正在尝试从 SUSE 存储库进行更新，但我做不到。例如当我运行这个：
# zypper refresh
我得到：
Refreshing service 'cloud_update'.
很长一段时间，然后我得到：
Timeout exceeded when accessing `'http://download.opensuse.org/repositories/server:/database:/postgresql/SLE_12_SP3/repodata/repomd.xml'.`
VPN 网关日志表明：
D sending DPD request
D generating INFORMATIONAL request 878 [ ]
D sending packet: from [Google IP address here][500] to [my IP address here][500] (80 bytes)
D received packet: from [my IP address here][500] to [Google IP address here][500] (80 bytes)
D parsed INFORMATIONAL response 878 [ ]
到底是怎么回事？SUSE 存储库是否已关闭？
如果我将上面的链接放在浏览器中，我会得到：
