Rak not connecting after flash 64 go card

Hello, I have a hs that I bought in 2021, I used it directly in the same year for a few months and it worked, after a few years I try to reconnect it in an apartment 400 m from the old one, I detect it, but it is always offline, I bought a 64 GB SD card on aliexpress, and I flashed the firmware with the version https://objects.githubusercontent.com/github-production-release-asset-2e65be/467326555/4952e667-dcd9-4e93-907b-3dd71defc93e?X-Amz- Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=releaseassetproduction%2F20241121%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20241121T1 33353Z&X-Amz-Expires=300&X-Amz-Signature=db33fbf610e59e6428e6a4c45ad45b013220c7e69c6f7d5922174002f94d061a&X-Amz-SignedHeaders=host &response-content-disposition=attachment%3B%20filename%3Dhelium-rak-2024-07-08.zip&response-content-type=application%2Foctet-stream that I think is the last one, and I followed the tutorial Getting Started with RAK/MNTD : Nebra Ltd
I had (next to the ethernet input) the green led flashing slowly, and the orange one is fixed, and in front (next to the SD card input) I have the red led fixed, and green led flashing too,
and I left it for 3 days now, but my hs is still offline on hottyspoty, and I can’t find it with the bluetooth scan on the helium wallet app or the old helium app, I try to access the interface via llIP, but I have a blank page with no response,
do you have an explanation for these clues please?
