Package Error : Two or more requests failed

[cognosda]

I just published a package to my test environment. When I try to open the package using report studio, I get an error saying "two or more requests failed" Screenshot attached.

All the file paths mentioned in the error messages are pointing to the files in the following path : /c10_64/webcontent/camcrypto

When I check mob.log in /c10_64/logs directory, I see the following message:

2015-07-22 11:50:38,320 [pool-4-thread-1] WARN com.cognos.mobile.server.apns.APNSCertificateExpiredChecker - Your Apple Push Notification Certificate expired 92 days ago.
2015-07-22 11:50:38,359 [pool-4-thread-1] ERROR com.cognos.mobile.server.apns.APNSCertificateExpiredChecker - Exception caught while checking certificate expiry. Notification email failure - Unknown SMTP host: mailserver (code 2000)

java.security.cert.CertificateExpiredException: NotAfter

I am not sure if the error in mob.log is related to the error I am getting when opening a package in report studio....What could be happening here?

Thanks for your help.

We re-generated crypto keys but this error had nothing to do with Crypto keys. In Cognos server configuration, I had "localhost" everywhere under "Environment". When I replaced that with the machine name, and re-tested the package the issue was gone.

This can be closed now.
