I am attempting to access a Jira page for a group project on my laptop, but no matter what browser I use (Firefox, Chrome, Edge), I keep getting this page and error message:

Screenshot 2026-01-12 154322.png

The status page says that all pages are operational, and it seems to be just my computer, as my groupmates are having no issues. Here are the error messages I get after inspecting the page:

1. The resource from "[my .js source]” was blocked due to MIME type (“text/html”)  mismatch (X-Content-Type-Options: nosniff).

2. Loading failed for the <script> with source "[my .js source]"

3. Uncaught SyntaxError: ' ' literal not terminated before end of script

I am unsure as to why this is happening, and any help would be greatly appreciated.

Hi @Kai McMeniman 

 

Did you try to create new page and see if issue still exist? Also make sure that you are not logged in with other atlassian account.

 

Regards,

Seba

Hi @Kai McMeniman 

Please clear all your browser cache and cookies, also make sure your browser version are up-to-date.

Disable any browser plugins and.or revert your browser to default settings.

This is a local PC issue, otherwise connect with your company IT department.

Also if someone provided you with a link, don't use this, but try the main link of the instance.

example: https://<name-of-the-instance>.atlassian.net
