Mobile Access application changing between PT and HT

[NorthernNetGuy]

I have a web application I'm trying to add to our Mobile access portal. I can reach the webapps log in page, which uses SAML. 

The login process uses azure AD, and after that, redirects back to the web app home page. The page only partially resolves.

I have the web app set to use Path Translation, with cookie handling on the gateway.

I notice that even when it is set to path translation, the url starts as  "https://sslvpn.site.com/sslvpn/PT/https://SomeApp.site.com/HomePage.do "

and after ~ 30s changes to

"https://sslvpn.site.com/HomePage.do?view_type=my_view"

which indicates it has changed from PT to HT.

I notice in chrome developer tools it gets stuckon a "https://sslvpn.site.com/sslvpn/Portal/GetSetCookies" request

I've tried various combinations of translations and cookie handling without success.

Anyone have insight into this issue?

What version/JHF?
What web app is it?

[NorthernNetGuy]

R81.20 / JHF 53.

Its an on prem instance of manage engines "servicedesk plus"

I think I may be wrong about it changing from PT to HT, the URL doesnt match what HT would do. The URL does seem to be getting manipulated, possibly by the webapp.

I want to try doing HT as it may fix the problem, but I haven't implemented it yet. I need to make several changes before I can enable it.

Not all web apps can be successfully used through MAB.
Usually it's Javascript related, which is notoriously difficult to rewrite in a compatible way.
