Running multiple websites on a Linux server and hitting a 421 Misdirected Request error? We’ve been there, and we’ve fixed it.
At Infomaze, we recently resolved this issue for a client, and we’re here to help you get your site back online—fast.
Let’s dive into what this error means, why it’s a problem, and how we can solve it for you.
Imagine you’re running several websites on one Linux server, all sharing the same IP address. Everything’s working fine—until suddenly, one of your sites goes down. Visitors are met with a strange error message: “421 Misdirected Request.”
This error usually happens when the server gets confused about which website to serve. It’s caused by a mismatch in something called Server Name Indication (SNI). SNI is like a label that tells the server which website a visitor wants to access. But if the SNI isn’t set up properly, the server may not know where to send the visitor, so it throws up a 421 error.
Your site’s offline, turning away customers.
Search engines might drop your site in rankings if it’s consistently unavailable.
Nobody likes seeing an error page instead of your awesome content.
We recently worked with a client who was dealing with this exact problem. Their Linux server was hosting multiple sites, and the 421 error brought everything to a screeching halt. Here’s how we got them back on track:
We jumped into their server, checked the setup, and spotted the SNI mismatch causing the chaos.
With a few tweaks to the server’s configuration (think Apache or Nginx adjustments), we got the right websites talking to the right SSL certificates.
The result? Their website was back, their visitors were happy, and their SEO stayed safe. No more stress, just a smooth-running site.
A downed website isn’t just annoying—it’s bad for business. Every minute your site’s offline, you’re losing traffic, customers, and potentially your spot on Google. The 421 Misdirected Request error might sound technical, but the fix doesn’t have to be. We make it simple, fast, and stress-free.
