Issues in connecting to Jenkins

[basilboonk]

I am new to this plugin and I am trying to connect to Jenkins
My jenkins URL is with a load balancer ip address mapping to port TCP 443

Jenkins URL : http://ipaddress:443 (No SSL configured as of now).. while using this I am getting the server unreachable error.

I was able to telnet to the same IP address on the port 443

-bash-4.2$ telnet IPAddress 443
Trying IPAddress...
Connected to IP Address.
Escape character is '^]'.

Also the curl connectivity using the URL trigger the build

-bash-4.2$ curl -v http://ipaddress:443/git/notifyCommit?url=https://username@GIThostname/git/scm/san/sample_application.git

• About to connect() to ipaddress port 443 (#0)

Scheduled polling of Test

Also tried adding an entry in the /etc/hosts file... and tried using a hostname, but the bitbucket doesnt pick the name and throwing a DNS error (unresolved host)

Am i doing anything wrong here.

Did you test connectivity between the bitbucket server and the load balancer? If you're testing this all client side it could be a networking issue.
