question!!: how can configure strongloop handle multiple instances of same server/server.js ? read configure stored redis session, guides talks express + redis stored session management. think different approach.

thanks in advance!

it seems not persisting accesstokens on common datasource running servers/processes.

try inspecting model-config.json file , verify datasource accesstoken model shared.

this not shared between servers/processes:

"accesstoken": {   "datasource": "memory",   "public": false }, 

this shared between servers/processes:

"accesstoken": {   "datasource": "mysqlds",   "public": false }, 

*where mysqlds stored on mysql
