Also in the remote server config it shows, "
Address looks good, but a connection could not be stablished."
But i can access the same URL through my browser

</html> something wrong with your proxy sever setting IMO,
generally speaking, curl a Jenkins main page should return 200 or maybe either 403 or 401 if any security settings were configured, even with a proxy server.
for example,
[xxx@xxx logs]$curl -I http://myjks/01/
HTTP/1.1 200 OK

I don't think this is a bug.
Update: updating the parameterized remote trigger plugin fixed the issue, but there is a different error now
