Blank screen issues

This might be partly related to https://github.com/fonsp/Pluto.jl/issues/1583

I started to use Pluto again and created a few notebooks for teaching. Today, when accessing the Pluto web UI, I only get a blank screen and the page is stuck at loading. Chrome displays sometimes "localhost took too long to respond" or simply hangs with a blank page.

I am using

  [c3e4b0f8] Pluto v0.19.32
  [7f904dfe] PlutoUI v0.7.53

with Julia 1.9.3 on macOS M1.

I tried the following:

• reinstalling Pluto, precompiling/building etc.
• removing all notebooks in ~/.julia/pluto_notebooks (is there any other place where Pluto stores some state files?)
• trying different browsers (also in Incognito)
• Chrome with Incognito mode worked twice for a few minutes, until I changed some using ... cells in a notebook and then everything crashed again saying that I should "restart the notebook" -> blank screen
• tried different ports
• deleted ~/.julia/artifacts and ~/.julia/compiled
• updated to Julia 1.9.4

I don't see any errors in the Julia session and I also don't see any errors in the web developer console (nothing is loaded).

In my Notebooks I was using CairioMakie and Javis / JavisNB.

Safari on macOS does not work at all.

How should this be debugged?

I tried all kinds of stuff, no way to get Pluto running. Is there any way to turn on verbose mode or something?

I even updated macOS to the latest Ventura version (13.6.1) and also deleted the whole ~/.julia directory and reinstalled everything. This issue is very likely OS related and I cannot believe I am the only one who faces this.

I don't have any VPN or weird network setup, also no firewall or proxy. Jupyter works flawlessly btw. and many other server-based apps either.

OK got it finally!

It was an HSTS policy which probably got its way to the localhost local storage in several browsers, probably from another web application which I ran through localhost. Phew...

For Safari, delete the local data under Settings/Privacy

I again hit this issue (twice today). The only way to solve it was again deleting the full local cache (which also deletes the notebook history). I think we need a solution for this. I still don't know how this happens...
