Vault login form is insecure?

I have been login to vault where last pass shown me that the page login form is insecure,

attached screen shot of the login![SS%20Bit|690x392](upload://4iuZ0bdI8c7A2UHCmfm1b6uzZ7h.

Please check

It must be a false positive because I just logged into the BitWarden Vault in Google Chrome with the Developer Console’s Network tab open (with Preserve Logs enabled) every single connection’s scheme to BitWarden is HTTPS/SSL.

Thank you for reply
