I tried from iOS and have the same result.
I tried with the admin account or a user account, but still don't understand why just browsing to:
http://myserver.local:22300/api/sessions even without authentication fails.
Does the server require to run in https ?
In my case it's http://__:22300
Here is my docker-compose file:
version: '3'
services:
db:
image: postgres:13.1
volumes:
- ./data/postgres:/var/lib/postgresql/data
ports:
- "5432:5432"
restart: unless-stopped
environment:
- POSTGRES_PASSWORD=dKRgwCrkmPU
- POSTGRES_USER=joplin
- POSTGRES_DB=joplindb
app:
image: joplin/server:latest
depends_on:
- db
ports:
- "22300:22300"
restart: unless-stopped
environment:
- APP_PORT=22300
- APP_BASE_URL=http://myserver.local:22300
