Symantec certificates require the installation of a intermediate CA to being fully trusted in all browsers. To download CA certificate, copy the entire contents of the first text box below (including the BEGIN certificate and END CERTIFICATE lines) and paste a new text document on the server. Don't use the "rich" text editors (such as Microsoft Word) to save the text document, as doing so could add extra line break C Haracters in to the certificate.

Recent customer feedback, Android phone opened the company's website, the issue of reporting certificates. And it's a Sementic certificate issue.

The middle process is very complex, and later on the official network found the certificate chain to fill in, restored.

Once again, 2 points are confirmed:

1 When a software problem, its official website is always the smartest.

2 when there are difficult problems, to find out the whole process of each step, combined with error information, will be able to solve the problem.
