HTTP Request not working, but does work in other request services

So im attempting to use a power automate flow to access the NIB Database(A database for all bridges and their reports), turn it into a CSV, and then return the CSV to a power app to then use as a list, but the HTTP request keeps failing. I'm getting "Http request failed as there is an error: 'A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. (www.fhwa.dot.gov:443)'." and it reruns it like 25 times and never gets a proper response. I know its not a problem with the website in general because i can easily do an HTTP request in python using requests.get and only pass in the URL and it works just fine. I think this may be a problem with it not being an api and instead its just a CSV hosted on a website, but I'm unsure why this would be a problem for the http connector but not requests.get. I have included the link. Any advice?

    it looks like an issue with large file

     

    Tried with a smaller one and it is working as expected

    I just tried with a different states dataset from the NIB that's only 24 records and its still failing. It seems to be some problem specifically with this website and the power automate HTTP request. I just tried it on the sample you sent and it works fine, but doesn't work on the NIB data, yet I can get it in python using get requests. Any ideas, like i need to add a header of some kind of something like that?
