problems when starting Node red

[Jorge Vargas]

Someone knows why when starting Node Red, the terminal shows: [error] [tls-config: AWS] Error: ENOENT, no such file or directory '/home/pi/pi_socket/TSRV.cert.pem'
Does someone know how to solve this problem?
My problem started when I installed node-red-contrib-pca9685. Node Red loads the localhost but does not load any node and flow scheme.

-?- install procedure
-?- complete log
