passwords – Stuck on CTF challenge

I am new to security and I am stuck at a CTF challenge hackthebox. And there is a challenge where I am not able to figure out what to do to break a sha512+salt hash. I have tried to use this site …

https://www.dcode.fr/sha512-hash which came back the word azerty. But when I type in the box It doesnt return incorrect. The hash is as follows

$6$ERMFdDVi$CMQa9VDhmde1hPJCL3K6x6IIPFIXseQUxF7MItaSzZkQefZ.0knezoOXKgLMGC.xa24V5ivsJl4PQGicQreyZ/
