This guide is intended to show an administrator of a PrimeKey SignServer Cloud AWS instance how to generate new Transport Layer Security (TLS) certificates.


This SignServer Cloud Documentation applies for the latest SignServer Cloud version.

For the latest SignServer Enterprise documentation, see SignServer Documentation.

AWS Documentation

For information on AWS Public IP addressing, refer to the AWS documentation on Public IPv4 Addresses and External DNS Hostnames.


New TLS certificates are needed in the following circumstances:

  • SignServer Cloud instance is shut down within the Amazon environment and the Public IP is released by Amazon.
  • An Elastic IP is added to the instance in place of the Public IP for persistence.
  • A custom DNS name is desired.

When using tools such as the ClientToolBox, the following error may be displayed:

"No subject alternative DNS name matching <instance ip> found".

If this is encountered, perform the steps in this guide.
