I'm trying to deploy planka with the following directories :

server is accessed at https://xxxx/tasks
client is accessed at https://xxxx/planka

In the client part, I've modified .env to set :

REACT_APP_SERVER_BASE_URL=https://xxxx/tasks
PUBLIC_URL=https://xxxx/planka

The client is build for production and deployed as static in the planka folder.

First, I had to modify config-overrides.js to replace <%= BASE_URL %> by process.env.PUBLIC_URL in order index.html works as static
But anyway, that's not the point of this issue.

The point is that with this configuration, the planka client keeps to try to access the server at https://xxxx/planka/socket.io/....

I've checked the code and it seems to be in api/socket.js where I see:
socket.path = `${Config.BASE_PATH}/socket.io`;

I think it should be
socket.path = `${Config.SERVER_BASE_PATH}/socket.io`;
where SERVER_BASE_PATH would be a new constant.

Am I wrong?

Hi! You're absolutely right, we've never tested this way of deployment. And it seems that your suggestion of adding SERVER_BASE_PATH would solve the problem.
