Terraform and JFrog

We are trying to connect to the JFrog Artifactory repo with the suggest method from artifactory:

#cat ~/.terraform.d/credentials.tfrc.json
“credentials”: {

And we always have this error:

There are some problems with the CLI configuration:
Error: The credentials “https://artifactory.itp.extra/artifactory:8443” block has an invalid hostname: port portion contains non-digit characters

We tried all kind of configuratio for host domain and always the same error

Best regard,
