Hello @drewmoseley @MarekBelisko @mirzak. I tried the WIFI connectivity, so my raspberry and my pc are connected to the same network but still can’t see my raspberry on the User Interface. I have a question how canr i know in which port of my pc mender is connected and how can i see through my raspberry if it is connected to mender server ? Thank you ---

You can check the Mender client logs by running: ```auto journalctl -f -a -u mender ``` To see if it is able to connect to the server. ---

You are getting “connection timeout” error when trying to access `192.168.10.1:443`. Is your Mender server running on a PC with the IP `192.168.10.1`? Can you successfully run `ping 192.168.10.1` on the Raspberry Pi? ---

No ping 192.168.10.1 from my raspberry is not successfull I mention that i did not do a systemd networking configuration I rather made a wifi configuration. ---

[docker.mender.io](http://docker.mender.io) doesn’t seems right to me ---

> [@MarekBelisko](#): > > [docker.mender.io](http://docker.mender.io) doesn’t seems right to me It is correct in a demo environment. > No ping 192.168.10.1 from my raspberry is not successfull This you need to resolve first, if you can not ping then you do not have network connectivity between the device and PC. Regardless if WiFi or Ethernet is used. So if you are connected to WiFi on Raspberry Pi, you need to figure out the IP address of the PC (Mender Server), be able to ping it, then you need to update `/etc/hosts` to make sure that `docker.mender.io` resolves to the IP address of your PC (mender server) ---

Well if you can not reach `192.168.10.1` then you must update this with the IP address that actually connects/routes to your PC. ---

Those are just arbitrary names we use in the demo setup. Since we use a pre-built certificate for TLS, they have to be associated with a known name. We then use the /etc/hosts file to define the IP address. It still seems like your issue is lower level networking since you cannot even ping outbound from the RasPi. ---

Yes it is a networking issue and apparently low level. I have a question for the artifact, in which langauge did you code ? [https://github.com/mendersoftware/mender](https://github.com/mendersoftware/mender) ---

The Mender client, mender-artifact tool and all server side components are written in golang. ---
