Hello everyone! 
My name is Edith and I am new to this community! 
As we are new to using MAS, I am writing this post hoping someone can help me with the problem I am experiencing!

We are working on the following version of IBM Maximo Application Suite: 
MAS Core: 8.11.18
MAS Manage: 8.7.15

We are attempting to expose MAS over the internet via NGINX reverse proxy, but we are experiencing some difficulties with the configuration, which for completeness I will attach to this post (_nignx.txt).

Initially we configured our NGINX proxy following the guide provided by IBM, but we had a lot of errors on Cookie management and CSP management, so doing a bit of research on this community, I discovered a post in which this guide was recommended: https://www.sharptree.io/blog/2023/2023-01-24-mas-reverse-proxy/, so we tried to integrate the js script suggested in the guide, which was really very helpful for the problem I tried to explain above.

At present, with the configuration I have attached and the addition of the js script, from the external domain I can get to the login page, log in, and navigate to the home page. 
The problem starts here: 
When I try to start the Manage application, it remains in a laoding state (I attach the manage_in_loading.png image to explain better). After refreshing the page, it seems to load (manage_after_refresh.png). 
However, I cannot navigate the different sections correctly, since when I try to make a selection from the left-hand menu on the page I am automatically redirected to the Manage start page.

So.. could someone help me understand if and what I am doing wrong in my NGINX configuration? 
Any suggestions, documentation or practical examples would be greatly appreciated!

Thank you all in advance!
