We've got an Umbraco (7.7.4) set up behind an AWS load balancer, SSL offloads at the LB, .lic in the bin folder
In umbracoSettings.config we've set:
<web.routing trySkipIisCustomErrors="true" internalRedirectPreservesTemplate="false" disableAlternativeTemplates="false" disableFindContentByIdPath="false" umbracoApplicationUrl="https://www.FULLDOMAIN.com" disableRedirectUrlTracking="true">
But it will still, at random, drop the licence and limit the send to 20 members.
Any ideas?
