============================================

If you receive the *Key invalid or validity too long* error, try generating a certificate with shorter validity:

```
# 90-day validity
openssl req -x509 -newkey rsa:2048 -keyout request_private.pem
 -out request_certificate.pem -days 90 -nodes -subj 
"/CN=RequestKey/O=YourOrg/C=US" && cat request_certificate.pem
 | grep -v "BEGIN CERTIFICATE" | grep -v "END CERTIFICATE" | 
tr -d '\n' && echo				
```
