I've been encountering an issue with importing apps for a while, and I'm trying to fix it.
The environment is Qlik Sense Enterprise, May 2025 version. The issue is the following : when I try to import a QVF with the "Import" from the QMC, if the QVF is too big (only a few Mo), I get the error message : "Failed to import app. Please check the log file." There is nothing of note in the logs, and if I import a QVF file of 160 Ko, there is no error.
The first curious thing is that the QVF file I try to import is a file I exported from another environement (typically, export from test to import in production), and I always make sure I export it without data, to be sure the file is not too big (5 632 Ko exactly for the file I used to test the import).
The second curious thing is that there is a workaround, with the choice of URL : -I get the error if I try to import the QVF while connecting to the QMC from my desktop. -If I try it locally, from the virtual machine where Qlik is installed, I also get the error if I use the same URL to connect to QMC than from my desktop. -But, If I try it locally, this time connecting to the QMC with the localhost URL (https://localhost/qmc/), I can import the very same file (5 632 Mo) that created an error.
There is supposedly nothing wrong with the URL I use from my Desktop, since I can import the 160 Ko file.
So far, I didn't find anything explaining this difference of results depending on the URL. Is there something I could try ?
