invalid certificate from BOINC clients

Scheduler request failed: Peer certificate cannot be authenticated with give

you must update/replace the ca-bundle.crt from the BOINC client. It looks like the file is outdated. Stop BOINC, replace the file and restart.

Changing of reporting primes to TOP5000
There was a change of the account SRBase from the T5k database admin. The user was changed to a project and I cant report any primes anymore. The CRUS project has now an "Anonymous" user where all the primes will be reported from now. In the description of the CRUS project SRBase is now included.

All other primes from you are not affected and will be reported as usual.
