Can I be logged into my account on more than one platform simultaneously?

For security purposes you can be logged into only one Cornèrtrader platform at a time. As soon as you log into another Cornèrtrader platform under the same ID, the system will issue a notification and force one of the platforms to log out.

The function causing the issue is the “Encrypted web scan” above. If you deactivate it, then it works. Fortunately you can add exceptions, by adding the Cornèrtrader website to the exceptions and it works. Bitdefender takes too long to scan our secure site for vulnerabilities and then our server times-out and disconnects.
