This PR: adafruit/Adafruit_CircuitPython_HTTPServer#25 changed the way imports for this library need to be coded. This PR changes to the new import syntax for the only current Learn project that uses the library.
I've also added a print statement to print errors if they are caught so that they won't be silently consumed. This can make it easier to troubleshoot if something has gone wrong.
