Tap service not working in tutorial notebooks

[ledwar04]

I am trying to start the TAP service, following the steps on the tutorials (eg tutorial 1): service = get_tap_service()

But, I keep getting an error, when I run the tutorials, and also when I run my own notebooks (that used to work).

To reproduce the error, try running tutorial number one, and it will happen at this command: service = get_tap_service()

Expected behavior There should be no error (and no output).

Screenshots I don't know how to insert a screenshot here. However, this is the error I get (in bold):

Hi, can you perform the following steps and let me know if it still happens?

1. Exit from the Notebook menu (Files->Exit without saving or Save and Exit)
2. Log out from the home page (data.lsst.cloud top right menu)
3. Start again, making sure you selected the Recommended image

and let us know what happens?

Screenshot for step 1:

Screenshot for step 2:

Screenshot for step 3:
