Disabling LocalCDN solves the issue.
Thanks for your report. Unfortunately, crossorigin and integrity attributes are present on this website. These attributes prevent the replacement. With Firefox you can remove these attributes, but the Chromium browser does not support this feature.
I have extended the online test (Domain-Check) a bit, so that you can also test these attributes without any technical knowledge.
Thank you 👍
Unfortunately, the error message is misleading. The problem was that the web server refused to connect. I adjusted the user agent of the PHP script and the error message. The localcdn.org webserver is now faking a Google Bot 😊
It should now work. However, it could happen that the web server to be analyzed refuses a connection at any time.
If this happens again, please create a new issue, because the online tool has nothing to do with the actual problem from this issue. This makes it clearer for everyone 😉
Deleting a branch is permanent. It CANNOT be undone. Continue?
