I tried it again just now.  My internet connection is currently
working normally, and it just failed again the same way.  If you tell
me what operation might be failing, I could try to test it.

i don't understand how this is trying to access a file -- I don't see
any file access functions in the backtrace.  The argument is a URL,
not a file name.  I don't know what any of these functions is supposed
to do.

Can you tell me any way to try to diagnose this further?
