Question when log in using tunnel

I can successfully log in using tunnel and open jupyter notebook. However, every time I log in, it always shows “System restart required” at the end and “channel 3: open failed: connect failed: Connection refused”. Anyone knows what happen and would it cause any problem?

Thanks!

I think the connect failed error is just your browser trying to reconnect to the jupyter notebook. If notebook works, you can ignore.

OK, thanks!

I got that message and rebooted the instance through aws, and the message went away

Thank you, Davi. I tried it and it works!

Yup, what @parrt said. It means that your Jupyter notebook in the browser tried to connect before your tunnel was ready. It’s no problem.

The ‘system restart required’ means that you’ve got updated packages that won’t work be upgraded until you reboot the computer.

That totally makes sense. Thank you!
