Using a non-standard port was causing the issue, indeed, Rax. I actually found this other post where they mention a couple of another valid ports: 80 8080 443 8443 8444 7990 8090 8085 8060. I’m using 8443 now and the 403 response is gone. However, I’m getting 502 now which is apparently caused because I’m using a self-signed certificate. Do you know how to avoid the trusted certificate checking for the developing phase?
Thanks in advance and for the previous response.
