@Phuturist I have a shelly 4 pro (old version) what has been working fine until recently.  
Now getting this error when correct IP and credentials. tried changeing to wrong IP, wrong user/pass and back again. also tried disable coap and restart with same error.  
is this a known bug? have not tried remove and re-add because i have alot of flows that then needs to be reconfigured.

updated to latest firmware of the shelly 4 pro but same problem both before and after firmware update so should not be related to that.  
web interface for the shelly pro works fine.
