How to add store artifacts on specified agents #4709

I am using QuickBuild 5.1.26
Save artifacts to an agent that has already been specified using 3 agents
I am using it after doing it. I added an agent to use as a new storage (my_specified_agent_04).
For normal operation, a login pop-up appears when downloading build deliverables after build, and the file is downloaded when you log in.

However, if you try to download the newly added build product of my_specified_agent_04, the login screen is not visible and an error occurs.

It's a 502 error code, but there's no problem with the firewall.
The product can be downloaded by wget.

How can I download it?

Please let me know.
