Work Environment

Question	Answer
OS version (server)	Ubuntu 20.04 ...
OS version (client)	Windows server 2016 ...
TheHive version / git hash	4.0.5.1, 9a530bc
Package Type	DEB
Browser type & version	Chrome, Firefox
Backend	Cassandra

Problem Description

After reboot of the hive system, where both frontend and backend is hosted. User avatar pictures disappear.
Browser asks for https://hiveurl/api/v1/user/~someid/avatar/someHashIGuess
Api responds with {"type":"NotFoundError","message":"user ~someID has no avatar"}

I have tried to see if i could reproduce the problem by just restarting either thehive or cassandra service, but this problem only happens when the system is rebooted as a whole, suspecting the avatar part to be part of a tmpfs.

Steps to Reproduce

1. Upload picture to some user.
2. Reboot system
3. Picture is no longer available.
