Cannot access wordpress admin page "404 page not found"

A link to your site would be helpful, as per WordPress Codex > Forum Welcome > Include as Much Information as Possible.

Sorry !!

Have you updated any plugins or your theme or WordPress yesterday?

The error for the wp-login.php is…

The page isn’t redirecting properly
Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

…this is a problem for your host. You should contact them and make them aware of this.

Yesterday No but on january 29 I have updated both google-analytics-dashboard-for-wp and Add to any plugin.

Even this morning I can still access my admin dashboard.

Then again, this is a problem for your host. You should contact them and make them aware of this.

Ok, thanks for the quick Reply NeoTechnomad.

Will contact my hosting company as soon as possible.

You’re welcome. Keep us informed.

It was because The login to wp-login.php was temporary disabled on the server due to recent brute force login attacks.

Now it is working fine .

Thanks you,

Best Regards,
