If I move my Windows Server Node, and it gets a new external IP address. The node stops working. I remove the node in windows, and reinstall. But is there a workaround ?

If your network address changes then this may affect incoming connections to the node, but generally it should not stop working altogether. Perhaps you could give more details of what exactly you are experiencing?
In any case, it should generally not be necessary to remove and reinstall the node. Instead, stopping and restarting the node service should be sufficient. If after that the node fails to start, it most likely indicates a corrupted database, which requires deleting (part of) the node’s database before restarting it. If you are experiencing corruption each time you move your node, then stopping the service before the move and restarting it after would be likely to help avoid this.
There is an issue with a new IP. To day I tested my node, moved it from Telenor IP, to Energi Fyn IP, and the internal IP is the same. Shut down the node, made a restart, but i does not show up i the block explorer.

The only thing that was changed, was the ip address.
Hi GSM,
These error messages indicate that some of the connections your node had to its peers have been dropped.
The node will automatically remove peers that are no longer responding after a bit, and then the messages will disappear (unless a new peer drops the connection, of course).
Are you still seeing these messages in the logs?
Best regards,
Kasper
Hello, yes there are lots of same messages in the log.
HI, now i have been doing at lot of testing. And the problem is Windows 2019, server, When i use Windows 10/11 or Ubuntu as a node, i can move from 1 to another external IP without any problems.
Thanks for letting us know. Perhaps there is some difference in how the network adapter is configured in Windows Server as opposed to other versions? (route print might give some indication if there is some difference in routing.)
Hi guys, did you get to the core of this error?
I am seeing a lot of these messages:
2022-02-20T17:42:44.812968200+01:00 ERROR concordium_node::p2p::connectivity - [sending to 79.78.40.101:8888] A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using a sendto call) no address was supplied. (os error 10057)
I’m running a Win 10 node.
Port 8888 is forwarded to node.
Just wanna be a good citizen 
Tim
Hi Tim,
Aside from this error, are you seeing problems with your node? This error can occur if the connection drops for various reasons.
Hi Thomas,
no apart from that the node seem to be doing its job.
We’ll just leave it, cheers,
Tim
