Guest users session expired when select an option

[Igor Almeida1]

When guest users select an option from a choice in virtual agent, this message is displayed:

It's something like: 'Your session has expired. Login again".

And when I look into console, I can see some failed http requests:

Any idea of a possible resolution for this problem?

Some util informations:

1 - Our widget is OOB

2 - All topics is enable for public users

3 - guest timeout properties are configured according the documentation

In my case some users are using anonymous session in chrome. This is not supported then I've guided the users do not use guest session in Chrome anonymous mode
