Dashboard redireccion to 8123 and no for 1880

Good morning.
The addressing to port 1880/endpoint/ui is not done correctly in the last update.
When clicking on the icon, it directs to 8123/endpoint/ui.
Can you fix it? Or is it just me?
Thank you and forgive my intrusion in the forum.
Or can you help me and tell me where I can change that address myself.
The actual version is 18.1.1
The icon is at the top right, it is a folder with a curved arrow.
In the last update it stopped redirecting correctly.
Where can I find the setting to change the port?
Thanks a lot.
