Issue SNI error

[thinkingcap]

Server operating system version

Ubuntu 24.04

Plesk version and microupdate number

Plesk Obsidian 18.0.71

Am getting this error across all sites on one server
"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"
Haven't made any changes in last 24hrs.

Any idea what would cause this?

Its being looked at by Plesk

echo -e "proxy_ssl_server_name on;\nproxy_ssl_name \$host;" > /etc/nginx/conf.d/fixssl.conf && service nginx restart

Is the work around.

Thanks for sharing!
Suddenly without any change my Ubuntu server with Plesk was not serving any website. This workaround fixed this very quickly.

Running config: Ubuntu 22.04.5 LTS. Plesk version: Plesk Obsidian 18.0.70 Update #2 Web Host Edition
Full error message i got on all sites:
Misdirected Request
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.

exact same problem as jpveen and same configuration !!
the problem is that I can not access with ssh from my computer. I used to access not so long ago. Only solution is using ssh terminal in plesk (in tools and settings).
Is the patch safe ?
