I am working on a LCA to which I have added some functionalities, that consists on some buttons that launch a UI defined on a IAS. The LCA is taking very long to launch and many times it leads to an error 504, like the one you can see in the following image.

I wonder if this has something to do with the IAS (the AS is only launched when the buttons are run so I understand this is not the case), or if it is something related to the LCA itself. Has anyone seen this before? Is there anything that can be done to solve this?

It is the tables that is taking very long to be populated. Exactly the parts that you can see that appear with a try again button in the screenshot
By saying that the app takes a long to load, do you mean the chromium and the components of the app or the data displayed in the app?
