Snap server install, same message duplicities Realtime API

Description:

Hello,

I have an issue using Realtime API when installing Rocket server with Snap and connecting to WebSocket endpoint wss://[ABC.DOMAIN.COM]/websocket of the server it sends duplicates of the same message and even some old messages that have been already sent before. For example, I am listening for private messages of some user and i am getting the same message with the same ID two times when user is posting the message.

When manually installing the server on Ubuntu, Realtime API works as expected only one message is sent to the socket.

Did someone face the issue?

Steps to reproduce:

1. Install rocket chat server thru Snap
2. Connect to Websocket API listen all events
3. Send any event and print messages that are received on socket end

Expected behavior:

1 message = 1 record, receiving two with same ID but slightly different timestamp

Actual behavior:

Server Setup Information:

• Version of Rocket.Chat Server: Output of snap list: rocketchat-server 3.18.7 1521 3.x/stable rocketchat✓ -
• Operating System: Ubuntu 20.4
• Deployment Method: snap
• Number of Running Instances: 1

Client Setup Information

• Desktop App or Browser Version: Chrome 106.0.5249.119 (Official Build) (64-bit)
• Operating System: Windows

Start by reproducing the duplicate WebSocket messages with Rocket.Chat Server 3.18.7 installed through Snap on Ubuntu 20.4, following the listed listener and send-event steps. Compare the received message IDs and timestamps with a manual Ubuntu installation; done means the Snap deployment delivers one record per sent message without old messages.
