Hello,
Can someone please help me with an issue I’m currently facing? I have installed Jenkins (Version 2.528.1) on a Windows Server 2022 instance in Azure. I have whitelisted the jenkins URLs in the Azure firewall to allow outbound traffic.
I am able to run test-netconnection from Jenkins controller successfully.
PS C:\Users\skatta> Test-NetConnection -ComputerName updates.jenkins.io -Port 443
ComputerName : updates.jenkins.io
RemoteAddress : 128.24.70.119
RemotePort : 443
InterfaceAlias : Ethernet
SourceAddress : xx.xx.xx.xx
TcpTestSucceeded : True
However, when I try to install plugins, I encounter the error below. Any help in resolving this issue would be greatly appreciated.
Thank you.
