What are you trying to clone from? GitHub.com? GHES? On prem azure devops? Hosted Azure DevOps? Something else?

Does it have a valid SSL cert or is it self signed?

What sort of auth mechanism is it trying to use? Basic? Kerberos? Something else?

i am also facing the same error during git clone by using libgit2sharp version 0.30
i am able to do git clone from cmd line script inside the server.
facing "could not initialize security context: The parameter is incorrect." error while trying to clone from libgit2sharp only

@ethomson
below are the details:
Cloning from, a private repository
it is self-signed
Auth mechanism is Basic

Another thing to mention is while testing it using "libgit2sharp-proxy-enabled" Version="0.0.0-preview.0.1901"
it is able to clone the repository successfully
(minor adjustment is made to adapt clone option changes)

@ethomson please find the requested details:
private repo
self signed certificate
basic authentication.
