How can I create a PKCS #12 file from a Origin Server Certificate?

[cursive vapor]

I have a Origin Certificate for my website which works but I need a PKCS #12 cert file for my Plex Media Server which is currently not secured.

I sent a screenshot of my Plex Media Server Network configuration.

I tried it in the past but I am not the best when it comes to Certificates…
Thank you!

If you have openssl installed, you can use it to convert the key and cert to a pfx file with

openssl pkcs12 -inkey inkey.pem -in incert.pem -export -out out.pfx

key and cert can be created and download from the origin server tab under ssl/tls

okay I will try that. When I first tried I also used OpenSSL but I did something wrong.

[cursive vapor]

okay so I have this out.pfx file now but what do I do with it?

[chilly socket]

upload it to your plex server and set the path

And the custom cert domain is my normal domain? Or also the subdomain I use for accessing plex?

[chilly socket]

the subdomain you use for accessing plex

I tried it now but I still get an unsecured connection

the encryption key is the export key I put in openssl right?

[chilly socket]

yep

[chilly socket]

do you mean a certificate error?

what certificate is it presenting?

I set Secured Connection to required and it said "plex.neutronnet.net took too long to respond"

[cursive vapor]

If I disable Required Secure Connection it just uses http

do you have port 443 forwarded? that might be a firewall

[cursive vapor]

Yes, I have a website running on the same domain and server. The plex port 32400. When you open plex.neutronnet.net the website redirects you to plex.neutronnet.net:32400. The website works normal with https.

cloudflare only supports certain ports - you can't use an arbritrary one like 32400
