Jira integration with GitLab getting error 401 Unauthorized

Hi,
I am trying to integrate Gitlab with Jira by using webhooks and powerscripts using SIL.

I have attempted the webhook using curl and it works OK passing the username/password as part of the URL using
curl -u <Username/Password> -X GET -H “Content-Type: application/json”

When I try using the webhook directly in Gitlab I get the 401 unauthorized, I believe it is associated with how I have constructred the URL itself in gitlab.

I created a token from secure/WebHooks.jspa placed this in the Gitlab Settings/Webooks panel, then encode the username/token using Base64 generating my URL as
Https:@

I am not sure what I am doing wrong but the webhook test shows 401 unauthorized.

Thanks
Allan

I am have converted my user name/password to base64 and my URL is
