Unable to login in the rut950 gui

Hello

I have a rut950 batch 098, I just added a SIM card in it. I want to activate the SIM data.

I log in ok in with the wifi and find a page asking username/pwd.

I tried admin/admin01 not working

I tried reset factory then admin/admin01 not working as well.

batch is 098 so I have no spécification password written on then admin silver

Does anyone has an idea ?

Thanks a lot

Malo

Can someone help me troubleshooting this?

Thanks

Malo
