Change wifi settings not working

I have 2 MHE inverters with an Intesis module built in which are physically unreachable. The wifi settings of the devices need to be updated due to a network change. I tried to change this using the local webserver of the devices, logged in as Admin user + pwd, but every time I try to update the wifi settings, access the Configuration tab or even click the restore the default button (no idea if this is a factory reset) the server replies with “ERROR Login Required”. Hence, I cannot update the wifi. I don’t feel like taking the device of the wall just to change the wifi. Simple question though, how can I change the wifi setting of the device?

Hello @peter_nl ,

Can you provide the Article number for the device?
