The solution is to modify a few lines in the apache SSL conf to disable clients from being able to downgrade the cipher.

This site will help generate the correct lines to disable bad ciphers. Need the apache version and ssl version. This fix is similar to previous SSL related fixes over the last year. https://mozilla.github.io/server-side-tls/ssl-config-generator/

So I tired Modern which includes -TLSv1 and that wouldn't start, dropping it works. But eventually we should also drop TLSv1 support. This adjustment should be applied to all osgeo SSL configured servers.

Is this still an issue or can we close?

Resolution: wontfix

I'm closing for lack of feedback. We need champions, no champion, no change.
