===== Another Approach =====

Obtain a certificate to allow the Proxmox web interface to work over https.

Then, add this certificate to the list of trusted certificates on the remote PC being used to access Proxmox.

<code bash>
openssl s_client -showcerts -connect 192.168.1.95:8006 /dev/null | openssl x509 -outform PEM > pve.pem
</code>

<WRAP info>
**NOTE:**  Where:

  * **192.168.1.95:8006** is the address of the web interface of the Proxmox hypervisor.
  * **pve.pem** is the output file of the certificate.

Then just add this certificate and set the rights to it **Always trust**.

Reload the Proxmox web page and access to the console should work.
