Bounces not processing

I'm trying to set up a bounce server and I get this address:
CDbException
CDbCommand failed to execute the SQL statement: SQLSTATE[HY000]: General error: 2006 MySQL server has gone away

I had set up one already, however, none of the bounces are being tracked. So I was trying to set up another one. At the backend, I have chosen the option to add multiple bounce servers ( Servers at once 10).

My hosting is with Digital Ocean.
8 GB Memory / 50 GB Disk / SFO2 - Ubuntu 16.04 (LTS) x64. PHP version is 7.0

I am able to upload new lists as big as 100k, launch campaigns, but not add one more bounce server. I am also able to add new sending servers.

As mentioned earlier, I don't see any bounces coming in to the first bounce server I set up. I am able to login via webmail for bounce@domain.com and tests to that ID from other email addresses are coming in. I have chosen this as the bounce server while setting up sending server. Still not a single bounce is strange. Could it be an issue with the MTA set up that's on another VPS that the bounce isn't coming through?

This is because when you add the bounce server, mailwizz tries to connect to it, and if it takes more time to do this than mysql is allowed to keep a connection active, then you get this error.
So i think, while you press the submit button to validate the bounce server, check the imap/pop3 server logs on the server that hosts your bounce server to see what is going on, i think the problem is there.
 
I tried with different bounce email domains (hosted on different severs) - but no luck :(

The mail server logs dont tell me much either. I had sent up FBL as postmaster@domain.com - this I was able to set up and I get mails there.
