Hello all,
I am facing an issue when accessing Nagios core UI that empty html files are downloaded randomly - it happened 5 times till now.
Has anyone faced this issue before?

Hi @alaa.hassan,
I don't understand what you mean that "empty html files are downloaded randomly".
Downloaded to your laptop/local machine? In your browser? Is there a file name?

Re: Auto-downloading empty html files
Hi Aaron, Thank you for your reply.
To give you more insights about the situation:
- I downloaded Nagios core, plugins and NRPE on a VM.
- I accessed the UI from my laptop using Firefox.
- It happened several times that on a random click or movement in the UI, an HTML file is being downloaded on my laptop.
those file had random names with html extension - the files themselves are empty with 0 KB.
I don't know why this happened - and there is no enough logs - I tried to make several actions on the UI to try to catch the network traffic but till now it didn't happen again. an example for the file name in co1mibra.html
So I was asking if someone has faced this issue before.
Nagios core version: 4.5.9
Nagios plugins version: 2.4.12
Nagios NRPE version: 4.1.1

Hi @alaa.hassan,
Thanks for the information.
I haven't seen a report like this before.
Core shouldn't be doing that, and I would be very surprised if it were. I don't mean to suggest that it couldn't possibly be Core, as we do fix the occasional Core bug. Still, there's no functionality or side effect of functionality in Core that would do that.
Especially as it is "on a random click or movement in the UI" I find myself wondering if this is some other software on your laptop, perhaps even malware or something else on the laptop.
So while it could be Core, I think it is just as likely, or perhaps even more likely that it is something else on the laptop, and you have noticed while using the Core interface. If you've never seen it occur any other time than while the Core interface is open in your browser, that would definitely be weird.
Apologies, this seems like a total deflection on my part, but I am reasonably certain the reason for the empty file downloads is to be found elsewhere.
Your thoughts?
