token not working in jupyter kernelgateway

Description

I have put my remote kernelgateway configurations in the setting like the following:

{"name": "my_server", "options": {"baseUrl": "http://ip:port", "token": "my_token"}}

but whenever I try to connect to a server which does not have any running kernels, it prompts me with a token authentication. When I try to connect to a server with a running python kernel, it won’t prompt me for a token authentiation.

I was doing fine with Hydrogen when this started to happen around few months ago, so I think it’s a bug somewhere around either Hydrogen or Jupyter Kernelgateway.

Steps to Reproduce

1. Setup remote kernelgateway using jupyter kernelgateway@2.5.0
2. Setup configurations in hydrogen including “baseUrl” and “token”
3. Hydrogen:connect-to-remote-kernel
4. Select remote server from dropdown, which does not have a running python kernel
5. hydrogen (or jupyter kernelgateway) prompts for token authentication

Additional context

This started happening few months ago. Until then, the “token” from hydrogen setting was working fine.

I second this (to some extent). Connecting to my remote kernel also prompts me to input the token manually, even if it is already given in the kernelgateway configurations in Hydrogen’s properties. This was not requested in previous versions. (atom 1.57.0, hydrogen 2.16.3, ubuntu 20.04.)

I will look into this over the next week. You can downgrade Hydrogen temporarily if you want
