MMDVM_Bridge keep alives

I have a DO droplet running MMDVM_Bridge to link a YSFReflector to my IPSC2 server

I seem to have an issue with keep alive packets, about once every 10 mins, sometimes more sometimes less, the connection drops and immediately reconnects. You can see here: ysf.nbdmr.net that 4000 will show in last heard every time it drops

E: 2020-06-23 21:36:01.393 DMR, Connection to the master has timed out, retrying connection
M: 2020-06-23 21:36:01.394 DMR, Closing DMR Network
M: 2020-06-23 21:36:01.394 DMR, Opening DMR Network
D: 2020-06-23 21:36:11.410 DMR, Sending authorisation
D: 2020-06-23 21:36:11.426 DMR, Sending configuration
D: 2020-06-23 21:36:11.442 DMR, Sending options
M: 2020-06-23 21:36:11.457 DMR, Logged into the master successfully

This all seemed to start suddenly a few weeks ago with no changes being made that I know of. All ports are open....just seems like occasional keep alives are failing and making it drop. Hard to have a QSO when the connection takes a crap every few minutes. Any suggestions?

Seems as if its the Miktrotik routers on the IPSC2 end causing a lot of packet loss, anyone ever have that issue?
