I've got a N152 Control Center with firmware 3.1.0. Now I want to upgrade the firmware to 4.x.x.

I installed the connection manager, version 1.1.1, as I understand that I need to use that to access the config page.

However, I cannot connect to the device. The HTTP UI is accessible on port 80. But there does not seem to be HTTPS access. Do I need an older version of the connection manager or is my device misconfigured?

Please check the status of the installed firmware version on devcie config page: http://[IP address]/config.php

In addition, please note that the latest updates consist of two files, which have to be loaded in sequence. The first one on FW upload page: http://[IP address]/upload.php The second one on devcie config page: http://[IP address]/config.php

For further support, please open an new support request: https://siemens.com/supportrequest

When I try to access config.php, I just get a 404 error.

Can I check which version I am running without access to that page?

I'll create a support ticket anyway.
