Since we are on SP 11.38.28 i am getting this error at AUX > Metalic. Anyone know what does its mean? 



Error - Description: [Media write operation failure] [Dedupe cloud media] [Failed to validate the cloud server certificate authenticity, either the cloud server presented an invalid certificate or a self-signed certificate. If the cloud server using self-signed certificate, please set additional setting MediaAgent CloudServerCertificateNameCheck with value 2 to skip peer certificate verification.]

Hi @Egor Skepko ,

Did you change the certs recently?

Can you check the error in cvd.log during that date/time?

Do you see Error = 44037

Best Regards,

Will send you a key privately to see if it helps.

If it doesn’t, it would be better to log a case with Support so Development can review.

Hello @Egor Skepko 

This error gets sent to us from the Cloud Vendor when they do not accept Self-Signed Certificates. The certificate could have changed or the vendor could have stopped supporting them but the error is a response from the vendor to our API requests and isn’t generated by Commvault.

You can either implement the key referred to in the error (which I suspect Sebastien has sent you) or you can implement a certificate signed by a Certificate Authority.


Thank you,
