I had the same issue and was able to resolve it with the following adjustments:

Previous scenario:
My setup included an Apache server with an SSL certificate, which redirected requests to another server where Harbor was running via Docker (without SSL, i.e., using HTTP).

Cause of the issue:
When trying to log in using the Docker CLI, the process failed because Harbor was exposing internal URLs with private IPs (e.g., 192.168.x.x) during the authentication flow.

Solution applied:

I edited the harbor.yml file;

In the hostname field, I set my public domain (e.g., luan.myharbor.com.br);

I uncommented and configured the external_url key with the full URL, including the protocol:
external_url: https://luan.myharbor.com.br

Then I reapplied the settings using the following commands:

cd harbor/
./prepare
docker-compose down
docker-compose up -d
