Hello, I upgraded to Matomo 4 some hours ago, and only Microsoft Edge on one computer is letting me sign in. I cannot sign in with Microsoft Edge on any other computer. Also, Chrome will not let me sign in from any computer. The error message is, : Error : Form security failed. Please reload the form and check that your cookies are enabled. If you use a proxy server, you must configure Matomo to accept the proxy header that forwards the Host header. Also, check that your Referrer header is sent correctly."
I have gone through the suggestion but to no resolve.
Can anyone please shed some light? Thanks, Fred.
