Teams Custom App with Personal Tab not showing on-premise JIRA webpage

[Mart Lehtmets]

Hello to everyone

I am quite new to Teams Custom Apps and everything, so I'm trying to figure things out here.

We want to present in our Custom application a Personal Tab (Custom Tab) to show our JIRA Service Desk page, so that employees could make their HelpDesk tickets straight from Teams application.

I have quite many questions now regarding this.

First of all if anyone has managed to do it (added JIRA webapage as custom tab in Teams custom application)? If yes, that would be a huge help.

We have configured the webpage as personal tab with the URL

We have tried several different versions

https://jira.<domain>.<>/

https://jira.<domain>.<>/servicedesk/customer/portal/1

but it wont load through, stays blank if trying with Desktop Application

With Teams web application it will show a bit more - "jira.xxx.xxx refused to connect".

We have configured JIRA agains AzureAD SSO using this tutorial
https://docs.microsoft.com/en-us/azure/active-directory/saas-apps/jira52microsoft-tutorial

And we can log in with our AzureAD users succesfully using regular web browser.

Not sure exactly what to do that Teams would load the webpage succesfully?!

Some articles talk about iFrame, but is that really the case? Maybe someone who knows more about this can enlighten me :)

Interesting! I'm also facing a similar issue but with our desk booking platform also using Azure SSO.

I've managed to figure out a workaround, which is switching to developer mode to then send an authentication request, which then allowed us to load the app from either normal or developer preview. After clearing the cache and logging back into Teams the same issue reoccurs so definitely seems to be tied to that log in event.
