Why after deployment URL request to a server get modified?

Hi everyone,
I’ve just deployed my app ( https://ec-blogapi.netlify.app/ ) and when it tries to make a server request, the URL instad of being myserverulr.com/folder/folder it becomes https://ec-blogapi.netlify.app/myserverulr.com/folder/folder . My app when runs locally works perfectly but on Netlify i have this problem of the URL Request

Can anyone please help me fix??

thanks

Probably not from the limited information provided so far.

What are the steps to recreate and see the request?
Can you share the repository?
