Hi, I just upgraded our site to latest, and when I try to open it in firefox, it gives me this error:
The site at [https://padpors.com/](https://padpors.com/) has experienced a network protocol violation that cannot be repaired.
The page you are trying to view cannot be shown because an error in the data transmission was detected.
I couldn’t also open the site in chrome. though the site seems to be up.
I would be thankful for any help or hints showing me what to do. as I couldn’t find any proper solution in the web so far.

Network violation error seems to be a side effect of the recent changes done in favour of eliminating the “Cannot load app” problem. I too get it when I wake up my work laptop from sleep and then a refresh is what it takes to fix.
This happens to me only on firefox.
Your site is loading fine here. Screenshot below.

The site is up for me. Since yesterday I saw your same error on many Discourse sites using Firefox 59.x.
It’s still this error ["Cannot Load App".... in Firefox sometimes. Refresh fixes it](https://meta.discourse.org/t/cannot-load-app-in-firefox-sometimes-refresh-fixes-it/85258)

It should be fixed when Firefox version 60 is released during the first week of May.
If you click on the Try Again button your site should load normally

@dax I remember some changes were pushed in discourse core to better handle the issue! Maybe that is causing this?

I don’t think, from what I know the only commit is this one for user offline
[https://github.com/discourse/discourse/commit/d2d3c7d24e733b1db8bd187df1f2b004d18d6ca2](https://github.com/discourse/discourse/commit/d2d3c7d24e733b1db8bd187df1f2b004d18d6ca2)
@Falco can confirm it or not.

many thanks for your responses, I still can’t open the site using either firefox or chrome. may it be due to slow web connection? or may you let me know what browser you use?
p.s. I agree that the site is up, as we haven’t got the down-message from up-time robot.
