Indy Agent Demonstration problem: Alice´s web server error.

[jlagop]

Hi. I followed Indy intallation guidelines from https://github.com/hyperledger/education/blob/master/LFS171x/indy-material/nodejs/README.md
Everything worked during installation, no trouble. All dockers start properly but Alice´s one. The docker starts ok, but there is an error (see below) and I can´t reach its web server for carrying on the exercise. Does anybody know what could be done to fix it? Log output:
