website via NPA and timeout

[RobinT]

Hi community, 

we are facing issues with several of our websites accessed via NPA:

Reaching the website is working without any issue, but if you let it in background for a while and come back to it, sometimes it falls into error without possibility to refresh the page and make it work. User needs to disable/enable agent to make it work again.

Anyone faced similar issue ?

Thanks, 

Robin
