Web-based VPNs establish secure connections using SSL/TLS certificates to authenticate the server and encrypt traffic. If this certificate has expired, web browsers will deem the host untrustworthy, producing "untrusted host errors" and halting the connection before authentication can occur.

All modern web browsers inherently support SSL/TLS, and an "untrusted host error" points to a problem with the server's certificate validity, not a deficiency in browser capability.

If a user's account were locked, the error message would be related to authentication failure (e.g., "account locked" or "invalid credentials"), not an "untrusted host" error, which occurs during the initial secure connection setup.

Reaching a VPN's seat license maximum would typically result in a message indicating capacity limits (e.g., "maximum users reached"), not an "untrusted host" error concerning certificate trust.
