Hello, what happens ?
I have the same on a Win7 and Win 10 machines. And also on ODLK1 (Latinsquare) !
Very strange "project server....down"
On project page, all seem running.

Not sure if this is a BOINC CA CERTIFICATE ERROR or that it's a PROJECT CA CERTIFICATE ERROR.

Get the following error message across all 6 of my PC's (Windows 8.1, Windows 7, Windows VISTA and Window WINE under Ubuntu) this morning (US time) on TWO projects iThena and WuProp
HTTP error: Peer certificate cannot be authenticated with given CA certificates
Running latest stable BOINC 7.16.11 Windows x64

Happened shortly after 9:00 AM local time (US CENTRAL TIME), Add +5 hours to get UTC TIME OF 14:00

Not sure if it affects any other projects. As far as I can see the SSL Security certificates for the two projects are NOT expired and are current.

...

16:42 UTC EDIT TO ADD>>
BOINC communicates with / Send / Receive tasks from my other two active projects on the pc's Minecraft and PRIVATE GFN with no certificate error messages

Hello Natalia,
Thank you for information.
It is really a problem of security certificate on your side.
Not your fault, but your project admin.
The same for yopur second project (ODLK1).
With you reference, I could solve the problem.
But it is not the way of doing from your system administrator.
Best regards

This is an Expired Certificate issue that does not belong to this or any other projects,

It is a certificate that has expired called IdentTrust DST Root CA X3 that has run from the year 2000 to September 30 2021 and has now expired. Let's Encrypt is the company supplying the certificate.

It deals with HTTPS access to the Web and will stop access if you are using it.
It can't apparently just be extended, and affects most devices prior to 2017. Windows XP Service pack 2 is affected but service pack is not (to a degree), lots of Apple devices and old phones will stop working and can't access the web.

There is a replacement Certificate called ISRG Root X1 and you can get it in a more recent CA Certificate bundle.
Some people have copied the version running in a recent Linux (which does not seem to be affected, probably because Firefox is the only browser that does not rely on the computers certificates to access the net) and then copied that into their Windows machines which seem to have fixed the problem.

I updated my CA Certificate bundle and found that only Latin Squares (ODLK1) and ODLK were the only two projects that stopped working.
Even with the updated certificate I had to Remove and Add back each project to get them to work again.

All working again now.

More information is available on the net see Let's Encrypt expiration

Thanks.

In the same time

The full solution would be a release of an updated client - which is long overdue, anyway.

Project server administrators may be able to take alleviating action, but that would be piecemeal, and not every project may have the necessary skills.
