For years, urllib.request.urlopen, which worked properly for years, began to give a 403 error?

Question

Python

There is a script (on a VPS server) that accesses the API through urllib.request.urlopen and receives data from the service that supplies this data.
For a couple of years everything was smooth, but for some time now some endpoints began to give a 403 error:

urllib.error.HTTPError: HTTP Error 403: Forbidden

options with substitution of different user-agents in headers did not bring results - the error remains the same.
Previously, this was not required at all.
At the same time, through wget, the result is saved without problems.
There is a similar problem on the working machine - everything opens with a browser, the script throws out a 403 error.
What can be done?

in the normal way, of course, you need to rewrite it for the latest Python
