I just tried logging in to gistlyn and when authorizing my github account it was trying to redirect to localhost:4000 rather than https://gistlyn.com
Should be resolved now, was in the middle of upgrading it to the latest dependencies but Microsoft deprecated the NuGet.Core v2 package we were using and had a community of architecture astronauts to design and develop the new NuGet.Client client making it unusable to use in projects like Gistlyn so I’ve abandoned the dep upgrade and reverted back to NuGet.Core v2.
