AWS installation continued

Hi,
I was able to deploy my solution to AWS (2 web servers, db serve, redis). I overcame initial issues (https://www.nopcommerce.com/boards/t/43836/help-needed-setup-failed-value-cannot-be-null-parameter-name-source.aspx ) by
- installing nop on web server 1 using non-web farm settings
- then modifying the web config to web farm settings including redis config
- and then copying the nop web folder to server 2.

The system seems to be working fine, load balancer sends me to server 1 or 2 and I get a correct anonymous cookie.
However after login the session does not seem to be working correctly - I'm only logged in on the original server.

Anyone had similar issues?

One thing I have noticed that standard Azure

This was resolved - forgot that machine key needs to be synchronized in the farm environment. This is described here:
