Just finished, my first on the site 
Just a quick question.
I was wondering, at some point in the process I decided to use ssh (by setting a key), but after about 5 minutes connections reset and all the temporary files would be gone. But the system uptime did not reset.
It happened twice, then I fell back to just using a normal reverse shell, and it did not happen again. Is this some type of protection at HTB? Or was it just an unlucky consequent and someone pressed the reset button on the web ui?
