After restarting the core, I get to the web interface
as soon as I want to open Node Red this message comes up (see picture)
After trying to open node Red several times, the message keeps coming back.
Then I tried to close Works and start the web interface again, but this only works after restarting the core.
I checked the network settings and they should fit.
Did you try using the 192.168.1.1 if it is the same there?
Do you reach your ctrlX CORE WebUI via the 192.168.1.140.200?
Does your PC have the corresponding IP for the 192.168.140.x subnet?
