[BUG] Proxy Protocol Breaks SSL

Is there an existing issue for this?

[X] I have searched the existing issues

Current Behavior

When Proxy Protocol is enabled on any subdomain, SSL breaks. This was working earlier today, nothing in the configuration changed, and it simply stopped working. On 2.11.0 but rolling back to 2.10.0 or 2.9.0 did not fix it.

Expected Behavior

No response

Steps To Reproduce

Add listen 443 ssl proxy_protocol; or listen 443 ssl http2 proxy_protocol; to any subdomain, even accessing over LAN is impossible. This was working as expected earlier today. It broke with no change in configuration. It is sitting behind HAProxy as load balancer.

Environment

- OS: Alpine
- How docker service was installed: docker-compose

CPU architecture

x86-64

Container logs

none worth mentioning, simply states "server ready."

access and error logs are similarly blank.
