4 months ago Hi, port closing problems are mostly in the combination of serialport as the underlying lib and the nodejs version, which has a very strict binding between both. Some OS' have a some lock time on serial ports or TTY's. That is the reason to have some reconnect timeout in the config node for control.

4 months ago I don't know, I'm running the default settings as in your screenshot. Looks fine so far in production, redeploying only single nodes now as necessary. Will keep an eye on it.
Feel free to close this issue. Also happy to help with debugging or testing.

Which node-red-contrib-modbus version are you using?
5.28.0
What happened?
Log during redeploy:
Maybe some kind of race condition when closing the port...?
Server
None/This is related to a node that doesn't connect to a server
How can this be reproduced?
Difficult, I guess. Here's the
