LHC@home

Hi,

For a while, due to my computer getting in higher temperatures than usual, I stopped using BOINC.
Then today, after fixing that, I decided to come back, but when trying to connect to LHC@home, I got
the error in the message log "peer certificate cannot be authenticated with known ca certificates"
I'm under windows XP and using an old version of boinc, and that may have made my situation worst,
but maybe the fix I used could work independently from os and boinc version, which is why I'm sharing it.

I first backed up my old "ca-bundle.crt" file in the BOINC folder (though I doubt I will either use this backup)
then got a new one from https://github.com/BOINC/boinc/blob/master/curl/ca-bundle.crt (I don't know how
"officiel" it is, but I don't think it could cause harm).
Then restarted boinc, but I got a new message telling me to reattach to the project with https (the true message
actually give the exact url).
After detaching and reattaching, it seems to work again (can't be sure until I get work, but there's no more errors).

I hope that my experience can be useful to others (though I wish people would just not run into any problem instead :p)

Thanks a lot for your post, Ano. I think it will for sure help other people having your same experience!

If you install a later version of BOINC, 7.2 or later, the updated certificate bundle comes with the client.
