"App is not responding. Wait or cancel?" in connection with "activityTrackerUtils.js"?

[Hauke Hörhold]

Currently, every Confluence page is experiencing an error when loading, with the message "App is not responding. Wait or cancel?" permanently displayed at the top of every page.

The following errors are visible in the browser console, which appear to be related to the problem:

activityTrackerUtils.js:56 POST https://xp.atlassian.com/v1/rgstr?k=client-REDACTED=javascript-client&sv=3.30.2&t=1767694095551&sid=REDACTED&ec=500&gz=1 net::ERR_BLOCKED_BY_CLIENT

and

Log.js:39 ERROR [Statsig] A networking error occurred during POST request to https://xp.atlassian.com/v1/rgstr?k=client-REDACTED&st=javascript-client&sv=3.30.2&t=1767694095551&sid=REDACTED&ec=500&gz=1. TypeError: Failed to fetch TypeError: Failed to fetch

 Clicking "cancel" results in the following error:

Is there a way to fix this for ourselfes or is someone working on this?

In Firefox there is some additional info, that it has to do with cross origin CORS stuff, it says: as it violates the following directive: “default-src ‘self’”

Hi @Hauke Hörhold 

Does this also occur in another browser than Firefox?

Are you running the latest version?

Did you try this in an incognito window?

Try to clear your cache and cookies.

I tried opening Confluence pages in different instances on different browsers and con't replicate this.

Hi @Marc -Devoteam-, thanks for the reply.

It seems that it is not client but backend dependend. My coworkers have the same error behaviour.
It occurs also in all spaces.

Nevertheless, I tried the following:
I tried it with Firefox 146.0.1 and Chrome 143.0.7499.170 (both are currently the latest versions).
I also tried it in incognito mode, same errors in both browsers.
I also deleted cache and cookies and installed a new Browser (Vivaldi), but that changes nothing.

Is it possible that it has to do something with installed apps? We have some, but nothing fancy, and it has been some time since they were installed. Two of those are selfmade (Forge apps), but they don't do much and the errors occur on all pages.

Hi @Hauke Hörhold 

Best is to see if you disable the apps and check.

Otherwise raise an issue with Atlassian Support, as this seems a localised issue on your instance

Other thins to check if you are on a company network or vpn connection that might block traffic.

Does it work on a private connection?

[Hauke Hörhold]

The connection makes no difference, from work, home or mobile connection is the same.

Thanks for the link to the support, I will try that!
