welcome to the notepad++ community, @Darren-Wogan and thank you for your detailed information, including your debug info.
However! … run as admin and set the proxy and retried and all of a sudden the new Plugins admin is working. Sure I tried this before without success, but its working now.
this is what i would have asked, if you wouldn’t have found it yourself already 😉👍
yes you are correct, and this is the most frequent hurdle for proxy users.
notepad++ has to be run as administrator, to set the proxy.
if it isn’t in administrator mode, at the time of setting the proxy, it will not give you any warning, but it will not be able to set the proxy.
sorry for the inconvenience and best regards.
