Since September 30th, Wuprop stopped responding on one of my computers. So I figured I would remove it and re-attach. Well, I can't. It just says Failed to add. Try again later. Any reason why?

You probably are getting the "Scheduler request failed: Peer certificate cannot be authenticated with given CA certificates" message.
READ through this forum here at WuProp LINK I started when it first appeared:

If so, you can do one of two things:

1) Follow one of several instructions in that explains how to do a TEMPORARY WORK AROUND/FIX ...

--- or ---

2) WAIT until a PERMANAT FIX is released with a NEW BOINC INSTALLER - how ever long that may be.

Thank you my friend, I have read that as I suspected it could be what's happening, but I am not getting that message. Just plain - Failed to add... Try again later. That's why it's so puzzling. But I'll read what's in the link, again, and try whatever I can... Many thanks!

G'Day KPX,
I also did not get those messages but a few sites were being blocked from access.

But with help from the net (my Windows XP machine was having some issues), I was able to update my certificates in Windows(that is not a straight forward thing to do) and away it went (Windows Explorer still does not work well but I don't use it so not a problem).

After updating the certificates I still had to detach and reattach both Latin Squares and ODLK projects to get them working again.

Using Firefox helps as it does not use the certificates on the computer but uses it own list and that is more up to date than Windows is.

The certificate that is causing the problems concerns HTTPS access to the net so that is why it stops things uploading and downloading.

Linux mostly was not affected as Firefox is a standard issue (at least on Fedora).

PS... Just found that iThena has not been working on my Windows 7 laptop and needed the solution that Den777 provided in the other post that Dr Who Fan links to about Peer certificates, interesting as nothing else was affected.
