Cannot connect Roborock S55 to LTE4506-M606

Adronalin

Hello,
recently I use the LTE4506-M606. My Roborock S55 cannot connect to this network.
If i try to install the vacuumer it said the connection timed out

It can connet to my old LTE router and a Fritzbox DSL router.

I have the latest Firmware on the vacuumer and router.
All ports are open and firewall settings are default.

Maybe someone can help

Hi Sir
You mean your Roborock S55 cannot connect to Wi-Fi right? May I ask if you set LTE4506 Wi-Fi connection no need password, will issue still happen? This action used to check if the problem occurred during authentication check progress. Thank you.
