Timeout when I try to download PDF from Reporting Module

[alejandroorg]

Hello,

I have a problem when I try to download anything from the reporting module. Is not related to the amount of data because I have tried that with a visualization with 6 events or with 30 millions of events.

Those logs are an example of the errors I get while I'm trying to download the PDF:
