checker-chromium.js "Error when running HTML checks: Error: Navigation Timeout Exceeded: 30000ms exceeded"

Hi,

I've got the same issue on Windows and Linux (same logs).
I've tested with my latest ePub... and an ePub already checked with Ace two weeks ago.
(my ePubs was epubchecked 4.0.2)

Ace 1.0.0, Node v9.11.1, Linux 4.9.0-6-amd64

*Same result on another Windows computer with Node v8.9.1.

Mmm, so the error happens with an EPUB that was processed correctly before?
I’ll try to reproduce. Would you be able to share the EPUB sample?

[garconvacher]

I can't in public due to copyright issues :)
I'll send you a PM on Twitter.

[garconvacher]

This was not an Ace issue...
After an update everything is OK on Windows and Linux.
Perhaps related to a puppeteer issue Timeout occurs when reusing a page. #2356 ?

[rdeltour]

Thanks for the update :-)
I re-open just until I double check that (since I was able to reproduce), and to remind me to look for the cause of the issue, which might be due to the way we're invoking puppeteer (and could potentially happen again).

Hello, I am a developer / contributor in the Ace App (ace-gui) project, which uses an alternative Electron-based Axe runner to the default Puppeteer-based one.
I fixed a similar issue that occurred randomly for some EPUBs. I would like to try the EPUB that was causing problems here. Would you be able to share it with me, please? Thanks!

[garconvacher]

Hello @danielweck !
Could you send me a PM on Twitter for sharing?

[danielweck]

I would prefer not using Twitter for this type of communication. Would you mind sending me an email at daniel.weck@gmail.com? Thank you very much!

[garconvacher]

Of course!

[danielweck]

Hello Ludovic, I forgot to update this issue discussion thread: I am not able to reproduce the bug with the provided EPUB. I tested Ace CLI (with the normal Puppeteer Axe runner, as well as the Electron-based one which is used by Ace App / ace-gui).

@danielweck , I have got a bunch of epub having simillar issues when processed using ACE via command prompt. I have already raised a separate ticket (#339) before I can see one. If you able to take a look I would be more than happy to send you one of our epubs. Thanks in advance!
