License Text does not match FileContent

Your reference to the COPYING file and the commit message does not match with the content.
On your website and in the license.md you reference LGPL
but the content of the file is GPL.
https://github.com/HangfireIO/Hangfire/blob/master/COPYING

so what is the correct license

Compare the license references on the website and in license.md with the contents of COPYING and the referenced commit message. First establish which license is authoritative with the project maintainer, then update the inconsistent references and verify that all named locations agree.
