Power cycle oven for 30 seconds?

What does that mean? Multiple help articles reference this with no further helpful details. Does it just mean turn it off and on again?

For context: I am having issues with connecting the oven to WiFi for the first time. I can see the oven network, just can’t connect.
Edit: actually weirdly it often says “Connected” after entering the oven code. When I check my phone’s WiFi settings, it seems I am actually connected to the oven’s network, but then it shows the “enter code” box again within the anova app, with no option to continue, other than to enter the code again. After that it says “Something came up. The application has cancelled the request to choose a device.” Back to code screen.

Thanks for any pointers.
