OAuth Error redirect uri did not match any configured URIs.. Bitbucket Slack integration

[P]

After following the steps outlined here:

https://confluence.atlassian.com/slack/use-slack-and-bitbucket-server-together-974387205.html

I was able to get a connection between the two applications, but when I was asked to confirm access to Slack from bitbucket I get the following error when clicking on the link:

OAuth Error: redirect_uri did not match any configured URIs.

Passed URI : http://XXXXXXXX.com/bitbucket/rest/slack/latest/oauth/redirect/TL7P64848

I created a self signed certificate and verified that when I open the bitbucket page I see the certificate. Using Apache & Openssl 

My question is, I'm I missing a configuration file that i need to edit in order to updated the "Passed URI"?

Do I need to configure any additional connector or proxy configs?

I Found a different add-on to use that works as intended.

What add-on did you go with in the end?

I ran into this same issue when I forgot to set the URL for our Bitbucket instance when adding the app to our slack workspace.

Maybe I should update the bitbucket.properties with the following:

scheme="https"
proxyName="XXXXXX.com"
proxyPort="443"

Any suggestions?

The issue is the redirect as stated in the error message:

OAuth Error: redirect_uri did not match any configured URIs.

Passed URI : http://XXXXXXXX.com/bitbucket/rest/slack/latest/oauth/redirect/TL7P64848

https://caci-nsis.slack.com/oauth/authoriz

What I cant find is where to properly place this "redirect_uri" 

I've tried placing the redirect_uri within the credentials portion of the slack integration page on the bitbucket server, but it does not seem to be noticing it.

Also the redirect_uris I've tried are:

https://slack.com/oauth/authorize

the passed uri in the error message

the bitbucket server, which is what the Passed url in the error message redirects to.

Documentation I'm using:

https://api.slack.com/docs/oauth

it just does not specify where to place the redirect_uri.. or i just dont seem to find it

Is this a step that would be needed as well?
