Error 403 when trying to connect Bitbucket Server to Jira Cloud via Application Link

[Intern]

When trying to connect Bitbucket Server to Jira Cloud via Application Link, I get the errors posted below. 

The Bitbucket server is running on port 8443.

There is a green link in the Bitbucket page when incoming from Jira but every other connection is a red link.

I also want to clarify a few things:

1. In one of the documentations, it says that the bitbucket server must be accessible either through port 443 or 80. However I see that other people using ports that other than 443 and have success when doing the application link.

2. Does the certificate in the bitbucket server have to be valid and NOT self signed or is this optional. 

3. Could it be these two factors that is causing this issue
