Collaboration Features Not Working

[ryanraposo]

Trying to get this to work on an Ubuntu 20.04 EC2 instance. I have a subdomain I'd like to use.

docker-compose.yaml

services:
  frontend:
    image: excalidraw:v0.1.0-b35a2c3-dirty
    ports:
      - 80:80

  storage:
    image: excalidraw-storage-backend:v0.1.0-b35a2c3-dirty
    restart: always
    environment: # docs https://github.com/alswl/excalidraw-storage-backend#environement-variables
      - PORT=8081
    ports:
      - 8081:8081

  room:
    image: excalidraw-room:v0.1.0-b35a2c3-dirty
    ports:
      - 8082:80

Any error messages?

[ryanraposo]

I did just add a STORAGE_URI, and now I'm getting

3/2023, 12:44:51 PM   ERROR [StorageService] Error: connect ECONNREFUSED 127.0.0.1:6379

'redis-cli ping' works. Same default port.

[ryanraposo]

When I try to get a share link:

undefined is not an object (evaluating 'window.crypto.subtle.generateKey')

When I click 'Live collaboration...' 'Start session' is greyed out.

[ryanraposo]

I think I'm closer now? back to redis, using auth... redis seems to be configured correctly. I'm using the elastic ip of my ec2 instance in place of localhost (or 0.0.0.0) and there are few/no errors.

I can't manage live collaboration, though. Not that I can see. Am I not using room correctly? BTW, I'm visiting the ip directly, as in 1.2.3.4 (after swapping it for localhost in the env/compose files)

redis seems prepared to manage scenes etc, but how do I go this crucial step further?

Live collaboration requires the https protocol, using Nginx

[alswl]

@yinhuihe is right.
Use HTTPS or use http://localhost .
