Has anyone experienced and found a solution to this problem?
upload new version of app. (n.b. i have appdir therefore other apps are not affected.);
restart shiny-server;
access any app without success, the computer says no:
An error has occurred
Invalid application configuraion.
Cannot read property 'connections' of null
a few minutes later without doing anything, the computer says yes and all apps are working fine.
server config:
