The forum is down after clicking on update!

Our forum is :

Since several hours, the site provides error 500 after receiving a mail for update and accept it.

What happen now?

The message says : it will work again later.
But when?
have I something to do?
Thank you for reply.

It’s hard to say without more information:

  • which release are you running?
  • which plugins are you using?
  • how did you install this instance?
  • have you attempted to rebuild via command line/ssh?

Recategorising from #bug to #support.

Hi Stephen,
It was the last update, 12 hours ago.
Now, it’s working again. @pfaffman did something and sent a mail.
But I 'm afraid to say that I Have no idea about what to do in a next future…

I suppose that I will not update discourse after this.
Thank you very much Stephen and thank you Jay.

I describe how to upgrade your two-container installation here: Managing a Two-Container Installation - Documentation - Literate Computing Support.

Well, a surprising number of people do that, but it’s not what I’d recommend!


I had the exact same issue and followed advice from @pfaffman on this thread. All you need to do is logon to the server as root and do a pull and rebuild of the app and it will all be fixed:

cd /var/discourse
git pull; ./launcher rebuild app

Of course, the bigger question is why a few of us are having this exact same issue (including the hamburger not working and then the admin page giving a does not exist error) during upgrades when it has never happened before?


Same with my forum.

I fixed with:

cd /var/discourse
git pull
./launcher rebuild app

Please check out all the categories, with your URL:, do you see all of these?

In my case, I see some. Not all of it. I’m investing why.

Hi guys!
I have upgraded and after that, it gives me a 504 Gateway Time-out error.
I did this, and it still doesn´t work.

cd /var/discourse
git pull; ./launcher rebuild app

Do you have any idea why it still not working?

I think you got your answer over here:
