Slash command error

I can't send a slash command to a server running on the mattermost VM itself or any other VM. I always get the following error: { "caller": "web/context.go:122", "err_where": "command", "error": "command: Comando com um gatilho de 'testecomando' falhou., Post \\"http://x.x.x.x:5000/bot\": dial tcp x.x.x.x:5000: i/o timeout", "http_code": 500, "ip_addr": "x.x.x.x", "level": "error", "method": "POST", "msg": "Comando com um gatilho de 'testecomando' falhou.", "path": "/api/v4/commands/execute", "request_id": "hp59hy97y7g3bcnki4yxmr117y", "timestamp": "2026-04-01 14:22:48.880 Z", "user_id": "9upbqjgo67ribrd9n3bpqe8dje" }

já permiti no config.json:

“AllowedUntrustedInternalConnections”: “x.x.x.x”,

Even so, I’m still making the same mistake.
