@Abdullah1224 it looks like it might have been cut off. Is there anyway you can copy all of it as text and post it?

The Web Worker Extension Host did not start in 60s, that might be a problem.

Guessing this is the issue. That does not look like a valid URL to me? More info on X-Frame-Options.

Any ideas on how we can help them debug this @code-asher ?

[benz0li]

@Abdullah1224 Try setting X-Frame-Options SAMEORIGIN instead of X-Frame-Options DENY in your nginx.conf.

Hi. I can confirm that version 4.2.0 can correctly create a Jupyter notebook.

@aghasemi can't tell you how much we appreciate you following up 🙌🏼 That saves us a ton of time. Cheers!
