Hey, this issue will be fixed in 2.0, it happens due to Version detection not finding a fitting value in a list of supported versions.
Sadly it'll take time to update the 2FA to 2.0 as there are many changes required to improve and fix the plugin, and testing is very limited (unless some people would volunteer to test the system on their server).
There are many challenges such as fixing some possible security vulnerabilities that might exist in the default proxy communication system (no redis or rabbitmq).
