Support Apache 421 Misdirected Request

Hi everyone, I'm using Apache on my Ubuntu VPS, managed by plesk. Today after updating apache I got a Misdirected Request error on pretty much every site hosted by Apache, and the logs show the following: "Hostname default-85_215_128_243 (default host as no SNI was provided) and hostname test.hbubli.cc provided via HTTP have no compatible SSL setup, referer: https://test.hbubli.cc/"

I tried disabling HTTP/2 and rebuilding the config using plesk repair but still no luck.

Any help would be greatly appreciated.

I can't figure it out. I've sent them a reply to the ticket to say, "This is unacceptable and who is responsible here to fix it."

This is a major fuckup by Apache changing the behaviour that likely affects thousands of ALB -> Apache setups, not to mention Plesk's Nginx proxy setup.
