AOS SSL connection error

Hi guys. I have a new problem, so please share.

This issue is a problem that works perfectly in the web version but does not work in AOS.

First, my development environment looks like this:

cocos creator: 3.5.1 version (there was the same issue in 3.3.2)
nakama : 3.11.0+c820042d
server os: windows 10
port : 7350

First, I am connecting to the domain. I’m using the certificate I got from the domain.

However, this works fine in the web version, but does not work when built with AOS.

The error message called from the server is as follows

[server side]
slot_nakama-nakama-1 | {“level”:“info”,“ts”:“2022-06-08T09:11:07.188Z”,“caller”:“http/server.go:3197”,“msg”:“http: TLS handshake error from remote error: tls: unknown certificate”}

and client side show this

[client side - aos]

2022-06-08 19:59:57.241 7899-8112/com.chamelio.magicka W/System.err: Trust anchor for certification path not found.

What I don’t understand now is that the web version worked perfectly, but I don’t understand why AOS doesn’t work. May I know how to solve this?

Looking here, in the case of android, an intermediate administrator CA is additionally required, is this a problem? If so, how should the middle administrator CA be registered in the current nakama?

Hey @Gandangf are you using Heroic Cloud?

Not yet. Should I use Heroic Cloud for using SSL?

In general we recommend Heroic Cloud if you are looking for out-of-the-box infrastructure such as SSL, loadbalancing, and horizontal scaling. We cannot provide infrastructure support to individuals who are running their own.

I see Okay. I’ll try to solve it myself.
