Can't acces when Receive "Lost Connection Error..."

[vivalgue]

Hello,

I have a problem when I try to reconnect to Qlik Sense when I receive the error "Connection lost ...".

I have QS April 2019 installed on a Windows Server with two virtual proxies:

1. default virtual proxy
2. windows virtual proxy

I try to change the session timeout with 30, 60 and 90 minutes and I always have the same problem.

I work on my PC (access with my windows credentials) and in QS I connect with a generic developer user and when I receive this error I cannot connect again to qlik sense.

Do you have any solution?

Kind Regards,
