I was able to duplicate the issue, and I did not have haproxy configured 
to do any kind of rewriting.

This is what I get with a verbose curl:

https://paste.elyograg.org/view/e95b70a0

This is what haproxy logged for that request, showing a 302 response:

May 24 10:01:41 - haproxy[299524] 192.168.217.199:59602 
[24/May/2022:10:01:41.656] solr~ be-solr/g8981 0/0/0/1/1 302 105 - - 
--NI 1/1/0/0/0 0/0 "GET https://solr.elyograg.org:8983/ HTTP/2.0"

Where would I do HttpConfiguration.setRelativeRedirectAllowed(true)?  
That looks like Java code, and Jetty is not embedded.  This is the 
jetty.xml in Solr 8.x:

https://gitbox.apache.org/repos/asf?p=lucene-solr.git;a=blob_plain;f=solr/server/etc/jetty.xml;h=e2f4ab095984aac27185a9879964862f9ba35d4d;hb=refs/heads/branch_8_11

I'm still digesting Uwe's reply.  To answer his question:  The proxy is 
https, Solr is http.

The relevant parts of my haproxy config can be found at the link below.  
The commented lines in the frontend are how I worked around the issue in 
haproxy -- handling root path redirect in haproxy rather than letting it 
through to Solr:
