ejabberd_auth_http stops making http call to check password on ejabberd 18.09

[damirci]

I have configured ejabberd_auth_http and it works fine but some times does not call check_password, and after restard the ejabberd starts working, here is the authentication log without any check password.

auth_method: http
auth_opts:
  host: "https://api2.test.com"
  connection_pool_size: 10
  connection_opts: []
  basic_auth: ""
  path_prefix: "/api/ChatAuth/"
auth_password_format: plain

this is solved by disabling auth cache
