Wanted UPnP/IGD device with UDN "uuid: xxxx" not found, aborting

I cannot fix this error. I have restarted the router & hasio; I have explicitly put upnp and an IP address in the configuration file. I have updated the uuid in the network config file to a UUID4 format. No joy. The frustrating thing is I have had this integration working several weeks ago. I am running Hassio 3.10 and HA 105.3.
Any thoughts?

After reading other posts, I concluded I needed to remove the UPnP integration that is installed automatically, as it is pointing to the wrong uuid. I did a snapshot. Made a copy of the following files for backup. And then removed the entries from core.config_entries, core.device_registry & core.entity_registry. After restarting, the system found the correct uuid address.

After you deleted the three core files. Did you have to reconfigure any other settings? Looking at the contents of these files, there are loads of messages and settings saved. It looks like uuid entry is only in the core.config_entries file. Maybe removing that file only will solve my issue I am having? UPNP is not able to find any device (ddwrt router in my case)

I didn’t delete the three files. I removed the entries (between the { } ) in each of the files. Check again, as a uuid for upnp is in each of the files. Do a ‘find’ search with a couple of letter from the uuid.

Ok. I’ve did a search again and this is the entry in the core.cnfig_entries file.

            {
                "connection_class": "local_poll",
                "data": {},
                "domain": "upnp",
                "entry_id": "61f40d02d6da406790c15aec25860435",
                "options": {},
                "source": "ignore",
                "system_options": {
                    "disable_new_entities": false
                },
                "title": "Ignored",
                "unique_id": "uuid:33EE3C6A-598D-7B96-FEC8-7065021D0B38::urn:schemas-upnp-org:device:InternetGatewayDevice:1",
                "version": 1
            },

I’ve tried searching either ‘upnp’ and ’ & ‘uuid:33EE3C6A’ for the other 2 files, but comes up none.

Since my last update, I have since removed upnp from my integrations. As a result, I cant verify your observations. Perhaps HA only use one file now. Sorry I cant be of more help.
