Mac: Unable to configure HTTPS endpoint. No server certificate was specified, and the default developer certificate could not be found or is out of date.

For 3 hours I was dealing with the title error nothing seems to work until I read the answer from hikrikunen where the key was deleting the localhost certificates in the system keychain and then running

dotnet dev-certs https –clean

and then

dotnet dev-certs https -t

Uptil the point of deleting the localhost certificates, the dotnet dev-certs commands were not getting me anywhere, telling me that there was no cert available, but refusing to add because there was a certificate available. Strange but I don’t understand fully what happened but now my API can be run on https locally again 🙂
