It turns out that when using node 10’s latest version the problem seems to be solved 🎉

However i have one last question : Despite upgrading to Liana v6, i get a message when starting my server saying that our current version “is DEPRECATED and will soon be BLOCKED”.  
Do you know the approximative date for this ?  
While debugging the login problem, i tried to upgrade to Liana v7, i spent quite some time having problems one after another, and i finally gave up on this one because the suggestions didn’t work for me : [Unexpected error: connect ECONNREFUSED 127.0.0.1:443 - #10 by schalkwijk](https://community.forestadmin.com/t/unexpected-error-connect-econnrefused-127-0-0-1-443/2507/10)
