core: Wemo integration creating non-stop SSDP errors in log

The problem

I am using the latest home assistant with a series of integrations. I have SSDP and Zeroconf enabled in my configuraiton.yaml file. As soon as i add the wemo integration, while it finds my wemo devices and adds them properly, i start getting all kinds of SSDP errors in my log files.

Here is an example:

2021-07-10 12:40:08 ERROR (Wemo DiscoveryResponder Thread) [pywemo.ssdp] Failed to send SSDP reply to ('192.168.1.108', 45072)
Traceback (most recent call last):
  File "/Users/u8915055/Documents/homeassistant/lib/python3.9/site-packages/pywemo/ssdp.py", line 426, in respond_to_discovery
    sock.sendto(
OSError: [Errno 49] Can't assign requested address
2021-07-10 12:40:09 ERROR (Wemo DiscoveryResponder Thread) [pywemo.ssdp] Failed to send SSDP reply to ('192.168.1.109', 53431)
Traceback (most recent call last):
  File "/Users/u8915055/Documents/homeassistant/lib/python3.9/site-packages/pywemo/ssdp.py", line 426, in respond_to_discovery
    sock.sendto(
OSError: [Errno 49] Can't assign requested address

THe strange thing here is that those IP address are google home devices (which are using the google cast integration and working fine). These messages happen every few seconds.

I watch my logging pretty carefully and this is the first time im seeing these… now whether this started with the last update or not i cannot say.
