https traccar unable to logout

I am trying to run secure traccar (https) using letsencrypt I configured httpd.conf as follow:

  ProxyPass /api/socket ws://localhost:8082/api/socket
  ProxyPassReverse /api/socket ws://localhost:8082/api/socket

  ProxyPass / http://localhost:8082/
  ProxyPassReverse / http://localhost:8082/

  SSLCertificateFile /etc/letsencrypt/live/cert.pem
  SSLCertificateKeyFile /etc/letsencrypt/live/privkey.pem
  Include /etc/letsencrypt/options-ssl-apache.conf
  SSLCertificateChainFile /etc/letsencrypt/live/chain.pem

I able to run login page https://example.com and I able to login into it.. but why I am unable to logout?
