I can't access my services remotely

I reset my router RUT951 with the version RUT9M_R_00.07.09.1_WEBUI and I updated to the latest version RUT9M_R_00.07.11_WEBUI. And then I installed the DDNS package to access my router and my services remotely.
My router or services are inaccessible page ( errors - connection timed out) when i connect to my DDNS address to a service or to my router outside my local network. But when I am connected to the wifi of my local network. I can access my services. how to solve this?

Hello,

Could you please check if remote HTTPS/HTTP access is enabled in System → Administration → Access Control?

Additionally, we have detailed DDNS configuration examples available, which might also be helpful. You can find them here: DDNS Configuration Examples.

Best regards,
