Cloudflare Certificate Problems

[Vincent Anis]

Hello,

I am new to Synology and having a hard time with importing my cloudflare certs. On the "Import Certificate Files" page after I have selected all 3 files and hit "OK", I get an error that says "Failed to Verify the server and intermediate certificates. Please try again." I have completely started over several times (new CSR and cert from cloudflare) and it never changes. Does anyone have some suggestions on what I should do?

If a answer is still needed!

You should import the cloudflare orgin server RSA PEM see doc. Origin CA certificates
Download Cloudflare RSA PEM
- Private Key field = your CF your domain.key
- Certificate field = your CF domain.crt
- Intermediate certificates field = the Cloudflare Origin CA root certificate
if all goes well then it should work and your Certificate is imported into Synology.

I do want to warn you that most browsers do not support CF certificates. They are seen as a self signed certificate. And it only works properly if you use Cloudflare proxy for the DNS settings.
