How do I troubleshoot login failures?

If you find that you can’t log in to your Matomo, following the error’s instructions will normally fix the problem. Otherwise, you can try the following steps below.

• If you can’t log in because you don’t remember your username or password, then view the forgot my password or username FAQ.
• Make sure that cookies for the Matomo site are enabled.
• Check browser add-ons are not blocking the website traffic. For example disable any ad blocker.
• It may help to clear the site cache.
• If you open the login page using HTTP, try if using HTTPS works.
• If you are using a proxy server, you must configure Matomo to accept the proxy header that forwards the Host header.
• If the shown error message mentions issues with the referrer, then you may need to check your Matomo setup, as possibly the referrer header is not sent correctly.
