I’m getting this error after installing the certificate & key:

[emerg] 809#0:  
SSL\_CTX\_use\_PrivateKey\_file(“/paging/site/config/server.key”) failed  
(SSL: error:0B080074:x509 certificate  
routines:X509\_check\_private\_key:key values mismatch)

I’ve tried this twice, (started over with a new csr, thinking I had  
screwed up and used the wrong key or something), and am still getting  
the error. I’ve double-checked to make sure that nginx is using the  
config file I expect, and that it specifies the correct locations for  
the cert & key.

How should I proceed in trouble-shooting this?

Meh, never mind. Supposedly same source of certificates as prior server  
installed within this same institution (I didn’t do the prior one), but  
this one is in root-\>mine order instead of mine-\>root order. Edited the  
cert file to switch them around, and now it works.
