When xmlsec1 version is pinned via env variable PYXMLSEC_XMLSEC1_VERSION, the url resolution logic returns https://www.aleksey.com/xmlsec/download/xmlsec1-<pinned-version>.tar.gz but this url is only valid for the latest version.
Older versions seem to be at https://www.aleksey.com/xmlsec/download/older-releases/
The download is failing with 404: Not Found
