1. Your Sticky sessions: IP address is used to serve the wallet with the same server, whenever possible. This means, that you can log in/log out of the wallet and see the balance, history and adresses as usual. However, if your IP changes it is likely that the LB will direct you to a different server (in order to keep work balance between all servers). As it is the nature of the Tangle that any node sees it from a different perspective, your balance and history might not be displayed completely. In order to resolve this, go to the "Receive"-section of your wallet and generate addresses until everything gets displayed correctly.
Vielleicht eine blöde Frage, aber bevor ich was falsch mache: wenn ich das Lightwallet nutze, muß ich ja neue Adressen generieren bis die Balances wieder da sind, wie auch in iotosupport.com beschrieben siehe Zitat oben, die Frage ist muß ich dabei diese neuen Adressen jedesmal attachen ("Attach to tangle") ?
