I am accessing via Steam.

I didn't have this problem earlier this morning (USA Eastern Time).

My problems began after lunch time.
The first problems was at the start of depth 19 (Coral Gate). I lost connection in game (jellies disappeared and charge attacks became unresponsive).
Then I was disconnected from the server.

Attempts to re-connect failed, so I waited an hour.

Now after sucessfully logging on and in the ready room, using the "Missions" tab to access the arcade and onto Coral Gate,
the loading screen would not appear and I would be again disconnected from the server.
Tried to log in again, the message says "Failed to connect to server" .

After another try, I decided to go directly to the acrade to acces the Coral Gate. When "attack" is engaged, nothing loads up. Repeated the "attack" three times with no response. And walking off the gate platform, player movement around me freezes, and I'm again disconnected from the server.

My internet is working. No change to my system.
Whats going on?
