## Symptoms

- When uploading SSL server certificate during integration process between SandBlast Mobile Dashboard and MDM, the following error message appears: "SSL error in address, please check server certificate validity"

## Cause

Uploaded certificate does not match the SSL validity requirements.

## Solution

Check if uploaded certificate matches the SSL Validity requirements as described below.

**Requirements for SSL validity:**

* Common name in certificate must match the server's name: e.g. if the MDM server you insert is **https://myuem.domain.com** , the common name of the server's certificate must match **myuem.domain.com** OR **\*.domain.com** (Wildcard supported).
* Issuer - must be a trusted CA: The issuer of the server's certificate must be a trusted CA, e.g. VeriSign, DigiCert, GoDaddy etc.
* In case the certificate is "Self Signed" by an untrusted CA, the customer must upload the server's certificate chain in the following format:  

  -----BEGIN CERTIFICATE-----  
  (Your Primary SSL certificate: your_domain_name.crt)  
  -----END CERTIFICATE-----

  -----BEGIN CERTIFICATE-----  
  (Your Intermediate certificate: DigiCertCA.crt)  
  -----END CERTIFICATE-----

  -----BEGIN CERTIFICATE-----  
  (Your Root certificate: TrustedRoot.crt)  
  -----END CERTIFICATE-----
* In addition, the below should also be ensured:  
  * Issuer of the Intermediate certificate should be the same as the Subject of the Primary Certificate.
  * Issuer of the next Intermediate/Root certificate should be the same as the Subject of the Intermediate certificate.
  * This continues until the last certificate.
