Can't update image from private registry via API

[Marvellvs]

I'm trying to update an image from a private Gitlab-Docker-registry using the following API request:
http://172.30.1.110:8080/v1/update?image=git.example.com:4567/testproject/testrepo

My image has the following name:
git.example.com:4567/testproject/testrepo

I've tried various variations of the image name with no success. In the logs I get the following:

time="2024-02-02T01:29:53-05:00" level=debug msg="Valid token found."
time="2024-02-02T01:29:53-05:00" level=info msg="Updates triggered by HTTP API request."
time="2024-02-02T01:29:53-05:00" level=debug msg="Checking containers for updated images"
time="2024-02-02T01:29:53-05:00" level=debug msg="Retrieving running containers"
time="2024-02-02T01:29:53-05:00" level=info msg="Session done" Failed=0 Scanned=0 Updated=0 notify=no

At the same time, if I make a request to the API without specifying an image, everything is successful, how can I correctly access the API if I want to update a specific image?
I also wanted to know if there are any other API methods, such as specifying container-name rather than image-name?

upd.: This problem only occurs if there is a port in the URL
