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

Question

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.

(3.6.1-conf-custom-m04.js:2:46950) 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’”

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!

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?

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.
