--- Comment #12 from Nick Bedford <webmas...@healthia.com.au> --- We also have the same AWS ALB -> EC2 Let's Encrypt setup and we have just started receiving 421 Misdirected Request responses despite our Apache2 being version 2.4.52 on the server. Nothing on our end has changed despite the server name indication working for the last six years. The only thing out of our control is the Application Load Balancer itself. If it never sent the SNI or was able to do server name determination at the Apache2 server in the first place, we would have had this issue for six years, but only since yesterday has it now surfaced. My only guess right now given that our EC2 is running Apache 2.4.52 is that the Load Balancer has changed and is now dropping SNI. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: bugs-unsubscr...@httpd.apache.org For additional commands, e-mail: bugs-h...@httpd.apache.org
