Running the below commands should solve your problem
- ovn-nbctl set-connection ptcp:6641:192.168.10.10
- ovn-
s
bctl set-connection ptcp:664
2
:192.168.10.10

et me know if you still face problems.
The reason for this is this commit -
https://github.com/openvswitch/ovs/commit/84d0ca5d00fe01b29163236d48fa0f9105687149
P
lease have a look at it.
Thanks
