I was getting this error message today when attempting to access support.ptc.com or community.ptc.com.  This was only occurring with Google Chrome and only for my main user profile.  Other Chrome profiles worked fine, and other web browsers (IE and Firefox) also worked fine.  Clearing the cookies for ptc.com resolved the issue.

Hi @TomU , 

Thanks for posting this, as well as sharing details on how you resolved the issue. Last week we upgraded our protection for the ptc.com and ptc.com/support sites and are aware that some customers and partners had issues accessing specific pages. We encourage others to post here, or contact us through the My PTC Assistant (#PTC Website & User Accounts # eSupport Portal) to report any issues which persist after emptying the browser cache, including cookies.  Please include the "Ray ID" that is quoted, as this allows us to pinpoint the reason for the block in our logs. 

In some cases, there are changes we'll need to make to our code or content, in others the issue can be client side such as using a specific browser plug-in.

Peter.

The same thing happened to me last week.

The only browser that worked, of the four I tried, was Firefox.

The other three, Chromium-based ones (Edge, Chrome and Brave) had the same problem.

Another peculiar thing was that, downloading the installation packages for Creo 12.4, I was able to do it for Creo and the Help Center while the error was coming out for the Creo Human Factors one.

For me too, clearing the cache later served to unlock access.

Hello!
I have the same problem, but clearing cache and cookies does not help. After clearing, I can access the sites, but the problem returns immediately after authorization, or simply when refreshing the page.
Additional information that may help investigate the problem:
- Used browsers: Microsoft Edge version 137.0.3296.93 and Google Chrome, version 137.0.7151.120. Official builds, OOTB (without any plugins, extensions, subsettings, etc.).
- A few Cloudflare Ray IDs: 953c0718ae17bf39, 953c09a10fbdee4c, 953c0b1f6d3bbffd, 953c1c3dbc61ee4d, 953c5edc2cc3bfe6, 953c66e74be2c3fe

For documentation purposes only:
I also had this problem once - on 30-Jun-2025.
However, a computer restart was enough for me to be able to access the PTC website again.
My IT colleagues suspected that the Zscaler service, which is installed on all our client computers, had briefly gone crazy.
