421 Misdirected Request error in Enhance Panel after recent Apache update

george

Hi everyone,

I’ve encountered the “421 Misdirected Request” error in the Enhance Panel, triggered recently by an Apache update on Ubuntu 22.04. This issue mirrors the scenario described in Plesk environments—specifically when Apache was updated to 2.4.58‑1ubuntu8.7—which broke HTTPS access to hosted sites .

Error details:

“The client needs a new connection for this request as the requested host name does not match the Server Name Indication (SNI) in use for this connection.”

In Plesk, the issue was resolved by adding the following to nginx’s configuration and restarting the service:

proxy_ssl_server_name on;
proxy_ssl_name $host;

This fixed the error immediately .

Could a similar fix be applied in the Enhance Panel?
Perhaps adding SNI-related proxy directives or updating the proxy configuration in Panel’s web stack could resolve the issue. Has anyone successfully implemented this, or is there a configuration workaround already available?

Thanks in advance for any insights!

Same problem here. Running Enhance on Ubuntu 24.04 and had to downgrade the packages.

HestiaCP panel also has the same issue and a fix as been issued: https://forum.hestiacp.com/t/nginx-apache-ssl-421-misdirected-request/19502/44

On Enhance all my webservers are running with OpenLiteSpeed, so I guess the issue will not affect me. But my Enhance Control Canel uses Apache. Can anyone confirm if in Enhance this issue only happens IF you have webservers running Apache and/or Nginx?

Thanks

We have several servers running Apache and Nginx on Ubuntu 24 that were upgraded to the latest Apache update today, but we were unable to replicate the issue.

Has anyone opened a ticket about this? Probably best to do that asap.

PS We run apache on our control server and have seen no issues. Perhaps that is due to us using Cloudflare on our control panel domain name.

This hit all our Plesk servers this morning, thankfully we are not using Apache on our Enhance servers...

The problem seems to occur when there is a proxy used infront of apache. In our case we are using an external haproxy. Sites that didn't use it worked.
