For anyone using WiseCP and getting an error trying to connect to HestiaCP.
Make this change to allow hash.
Under the WiseCP directory go to coremio->modules->Servers->HestiaCP
Open and modifiy the “api.php”
The function call needs to be changed from
$post[‘password’] = $this->server[“password”];
to
$post[‘hash’] = $this->server[“access_hash”];
