"Invalid origin in HTTP request, click to reconnect." Require docker env var for allowOrigin

[silycr]

Error presented after logging in

Invalid origin in HTTP request, click to reconnect.

Feature introduced in MeshCentral v1.1.21 is an allowOrigin tag in the config.json

FIX: Add option in environment block for acceptable origins, default true(all)

Solution for now is to modify config.json with

{
  "settings": { ... },
  "domains": {
    "": {
      "allowedOrigin": true
    }
  }
}
