Server connection lost, trying to reconnect issue.

Hello Everyone,

I am using vaadin 8 and getting “Server connection lost, trying to reconnect.” after some specific time period. and then user are not able to re-login and getting “webpage not available” error.

We have set session timeout to -1 “unlimited time period”.

can anyone please help in this case.

Do you have the closeIdleSessions property configured to true?
