I'm experiencing similar issues, logging out every 5-10 minutes too. Hopefully, they'll address this soon to provide a smoother experience.
When does the logging out happen? During in the middle of your active or during your inactive sessions? If it's the latter, then it's an understandable security measure
And then tested it using VPN, it was seamless and smooth login.
Be careful, you might end up having your account flagged, especially if the IP addresses point to countries that have been banned from using the casino. They are quite a number.
