For DoH and DoT listeners, a reconfiguration event triggers a creation of a new 'SSL_CTX' TLS context, and a destruction of the old one. The network manager, though, keeps using the old context which causes errors. During interface scanning, when a matching existing interface is found, reuse it only when it doesn't have a TLS context, otherwise shut it down and recreate with a new TLS context.
