Hi, I’m having the same problem now for the second time (after 7 days):

Using OH 2.4 and a MDT KNX IP interface here.
Bridge knx:ip:bridge "IP Interface"
[
type="TUNNEL",
ipAddress="192.168.0.53",
portNumber=3671,
readingPause=50,
responseTimeout=10,
readRetriesLimit=3,
autoReconnectPeriod=60,
localIp="192.168.0.40"
]
Restarting the binding helps.
Did you find a solution?
(Might be related: KNX2 stopps working after a while (received disconnect response status 0x21))
