SSL error on Client

[heroumi]

Hello SFS Team,

I have used SFS Overcast successfully with SSL.
Currently for some reasons I am moving to a personal server. However, getting an error with SSL. I installed SFS2x on Google cloud Linux, added SSL and opened port for 8443. I was able to access the admin page domain.com/8443:admin. but cannot connect from SFS Unity Client.

Below is my configuration, please take a look and can you give me some guidance? Thank you,

Hi,
your client supports both socket and websockets connections. Are both failing?
If so can you provide the exact error you're getting and specify which connection type you're testing with?

Also, when using websockets the InitCrypto step should be skipped entirely as it's not needed.

Cheers

Connection to SmartFoxServer lost; reason is: unknown

Hello, I got this error message.
Above code I took from SFS2x Demo matching on assetstore. and add encryption: InitCrypto.

[heroumi]

In addition, I use TCP sockets to connect. Is the control panel configured to open port 8443? Even though I tried opening it, I couldn't connect from the client. going to the web console with SSL still succeeds.

Just finished, I tried connecting using: private int tcpPort = 9933; and execute "InitCrypto". Successful connection result. So is this an SSL connection made or is it not using SSL? I really wonder. if you use port 8443, you will not be able to connect.

[Lapo]

Is the control panel configured to open port 8443? Even though I tried opening it, I couldn't connect from the client. going to the web console with SSL still succeeds.

Port 8443 is open by default (and it looks active from the screenshots posted here)
You can point your browser to https://<your-server-address>:8443 and you should see the usual welcome page with the link to the AdminTool. If you don't have a valid SSL certificate deployed you will see a browser warning saying that it could be "dangerous" to proceed.

Does this work, at least?

Thanks

Hi, I can access admin with ssl for port 8443. Only problem with unity client.
- If I choose InitCrypto and use port 9933 tcp the connection is successful.
- If not InitCrypto and using port 9933 will fail.
- If use port 8443 and InitCrypto it will fail

This is correct. SmartFoxServer communicates on TCP port 9933. You don''t need to change port in order to use SSL

- If not InitCrypto and using port 9933 will fail.

Correct. Your Zone is configured to accept encrypted connections only, so non-encrypted clients won't be able to access the Zone.

- If use port 8443 and InitCrypto it will fail

Correct. Port 9933 is the used for TCP connections and communication.
Port 8443 is only needed to initialize SSL cryptography.

Thanks for your information. Very helpful.
I would like to ask, Will the upcoming update of Smartfox still take place on SFS2X or will there be a new and better version?
