Ajax web interface issue, all browsers

Postby wrwindsor » Mon Mar 11, 2019 11:16 pm

OSE/FOSS version.

I recently upgraded Zimbra from something ancient (circa 2010) to 8.8.11_P2 by using zextras (30 day trial) to export everything and import into 8.8.11_P2.

For a short while, ajax worked for my account (FireFox), never worked for wife's account (Chrome, FireFox, McEdge). Then after trying to pull it up on other browsers, it quit working on mine too across the board.

I dug through the forums, found the "set default search to in:sent" trick, that didn't work.

Then P3 was announced, so I upgraded to it last weekend.

For me, Ajax GUI started working again (FireFox), wife still having problems. She logs in from work (another computer) and it works! yay.

An hour ago, I restarted FireFox on my laptop and the Ajax login quit working again.

I've tried clearing the cache'n'cookies in FireFox, I've killed'n'restarted FireFox. I've pulled up all three other browsers (Chrome, Edge, IE) and it doesn't work there, either.

I've also tried it on another (fresh install) W7 system with chrome and IE and it hangs there as well.

I've cleared the cache in Zimbra, I've restarted the server.

When it fails, it's the typical hang at the "Loading ..." grey box.

Where do I start looking for Ajax-related logs? This is horribly annoying.

Thanks.

A minor update to this...

If Ajax interface is wedged in FireFox, opening in any other browser mimics the problem.

If I log out in FireFox, I can open it fine in Chrome.

Starting to look more like a browser issue.

Another minor update.

If I log out of FireFox, get it up and running in Chrome, I can bring it up again (later) in FireFox and it works fine.

Or in other words.. it appears to be a bit random on when it does and does not work. I'll have to play with it more to narrow that down.

This is all 8.8.11_p3, btw.

The problem crops up when NoScript catches (and blocks) something trying to run scripts off of worldcdn.net.

It's not NoScript that's the problem, though. At the same time I can pull up Chrome (no plugins installed) and it fails there as well. Also, wife can pull up any browser on her system and it fails during the same timeframe (she doesn't run the 1337 plugins).

Given that it's https, I doubt there's a MIM attack/proxy doing this.

Does zimbra have some DNS prefetch code inside it?

You might want to re-apply P3.

They released it with an (unneeded) patch for Chrome (beta) that breaks Firefox.
So they re-released it (the day after IIRC) with the fix, without changing its name (it's still P3, not P4 nor P3b).

If you installed the first P3, you should re-download it and re-apply it.

Thanks for the tip, I'll do that soon and see how it goes.
