Proxy setting not working

Using Jenkins

Hi
I am using Jenkins 2.440.2 in offline mode. I want to update the Jenkins plugins.
For that i have configured http proxy in configure system page. But still i am not getting list of update/available plugins in plugin section.

Also getting error like: -

{8A3F1BE5-9E1D-4CE6-A07D-D087939A7E9B}
{8A3F1BE5-9E1D-4CE6-A07D-D087939A7E9B}1905×867 42.6 KB

Please let me know how we can update all plugins using CLI or UI.

It would help if you let us know your proxy configuration.
The url https://updates.jenkins.io/update-center.json redirects to another location, while https://updates.jenkins.io/ doesn’t redirect.

Hi Markus
Thanks for you quick response.
Please find the below proxy config details.

In the field Server you have to specify the hostname of the proxy server
10.*.*.*.* is in no way anything valid for that field. It’s not even a valid wildcard as it contains too many dots

Hi Markus,

I am using the correct proxy server details. Below are the sample proxy server ip address.
10.10.20.0

I see that the proxy is configured as 10. * . * . * . * which isn’t a valid IP address format since it has more than 4 octets making it have more than 32 bit. You should be using a specific IP address like 10.10.20.0 as you mentioned do not put a wildcard put the specific address and on top of that the wildcard you put has a wrong format.
