Error SSL after installation

I have this error after discourse installation
I install by docker, google cloud, plesk to port 3000


On subdomain:

502 Bad Gateway


On ip with port 3000

App root (ssh):
nginx: [emerg] cannot load certificate “/shared/ssl/”: PEM_read_bio_X509_AU
X() failed (SSL: error:0909006C:PEM routines:get_name:no start line:Expecting: TRUSTED CERTIFICAT


That doesn’t sound like you followed the official installation instructions.

I done it, but I change to port 3000
Because I have many port use for others, and I change discourse to port 3000 before map to subdomain

Discourse has to be installed on standard ports. What you’re doing isn’t supported.


See this meta install post for additional clues:


Yes, that’s exactly what I need

Hi, it’s install successful now
But its url is just http. It seems Let’s Engypt done, but not working for https

When I refresh, at first it is https. But it redirect to http at last.
It’s like having SSL, but “Not secure”?

Do you have any idea?

Your icons and images are all http, so you have mixed content. You have to change the http to https.

How could I do for https?
I got Let’s encrypt active but it has this problem

Hey @cmdntd

You may want to consider rebuilding your app and insuring your LetsEncrypt is installed properly.

Frankly, I have never used Plesk and always work directly on the OS like Ubuntu or macOS, so I’m not the best person to help you with Plesk.

Looks like you are making progress; so stay encouraged and you will have it all worked out (working) soon.


I don’t know if my dns has not complete
Today, I loggined and see https is perfect
