# Connect T4K UI hosted with HTTPS to another cluster hosted with HTTP or vice versa

When user has two Kubernetes clusters with T4K installation and they want to connect them using T4K's Multi-Cluster Management (MCM) feature, T4K expected the UI to run on same protocol viz. `HTTP` or `HTTPS`.

When both clusters T4K UI instances are not running on same protocol, the browser does not allow the connection to another cluster which has T4K UI running with HTTP or vice versa. It throws an error as `Blocked: Mixed Content` and the connection fails at the browser. This causes failure to add secondary cluster.

When a user want to connect the secondary Kubernetes cluster's T4K UI with primary Kubernetes cluster, as they enter the T4K UI URL in the Primary cluster's T4K UI, the `Kubernetes Distribution Type` is not auto-populated. The different login options for the secondary cluster which are populated by dex are also not shown.

Please follow the below steps to resolve this issue at the browser level.

1. User need to allow the `Insecure Connection` to the T4K UI running on HTTP protocol
   * Click on `Not secure` text next to `https://` URL from where the user is accessing the T4K UI of the Primary cluster
   * Click the option `Site Setting`
   * From the new opened tab of `Browser Settings`, go to `Insecure Content` setting and option `Allow` option from dropdown.
   * Go to original browser tab of T4K UI of Primary cluster
   * Click on `Reload`, if the option to `Reload` is not present, `Refresh` the browser tab.
2. Now, add the secondary cluster's T4K UI running with `HTTP` using MCM again.

Above steps should auto-populate the `Kubernetes Distribution Type` and different login options to the secondary cluster using dex.
