Anvil offline errors

I’m seeing a few Anvil Offline errors in long running apps, as well as :

“We could not find an app that matched your request.”

Hi @david.wylie,

Are these errors when you are running the app in/from the Editor or when they are deployed?


IDE, but sorry I meant to update that it seemed to have gone away (suffering with Covid is my main defence). So all good at the moment for me.

No problem. Let us know if you see them again and we will investigate.

I am having random anvil offline errors as well. At first I experienced only in the IDE, but a couple of weeks ago I got some reports from my users, that the website is not working. Nowadays I can see it pop up sometimes in my logs.

I saw some threads, where others experienced the same issue, where they concluded, that some browser extension may cause the issue. So I also tried their solution out. Deleted extensions, then cookies, then basically cleaned my whole browser, but the issue remained.

The most frustrating thing is that I can not reproduce the issue. It just occurs, when a function has to call the server.

I wrote an email to, hoping that we can investigate it further, unfortunately I did not receive any response.

The last time it occured, it was on 11th of July, but I can not figure out, what causes it.

Looking back at the logs, I noticed a slightly different error stating, that AppOfflineError: Connection to server failed (1006).

This issue has made some headaches, but hopefully it will be soon fixed.

I’m basically getting them every morning in the IDE, meaning I have to refresh the IDE tab.

It’s not too much of a bother, but it never used to happen.
