Like Sadrake, I have noticed that I can not complete a daily call from Tivo...
Unlike Sadrake I have not changed ISP's, and instead connect to the dev emulator (port 80). My ISP assures me that they have not begun using any form of proxy (and provided this rather handy link to verify it (which it does)).
Having been away for the last week I know it's not something I have done - it was working before and after I left, but failed while I was away... and as is usually the way when you go away, my internet connection dropped early on the 16th and did not come back up until I reset the router on the weekend - therefore the last successful call was August 16 @ 2:20am.
I'm running the 1.3 image and did note the HTTP/1.0 comment in the log (below) which is why I went first to my ISP.
FYI The entry in tclient.conf is:
127::210.48.107.133:80:::

If I try to wget the file from Orac, I get the following:

[TiVo [p1] /tmp]# wget 210.48.107.133/tivo/slice/nzdev.slice
--11:25:39-- http://210.48.107.133/tivo/slice/nzdev.slice
=> `nzdev.slice'
Connecting to 210.48.107.133:80... connected.
HTTP request sent, awaiting response... 404 Not Found
11:25:42 ERROR 404: Not Found.


However I can FTP (from PC) to the IP and find the file in the correct location (and download it to the PC). Tivo can ping internet IP addresses with no issues.

Any idea how to resolve this?
Cheers
Neil
