find_bridges throws multiple exceptions

Hi,

just trying to run discoverhue.find_bridges, which fails:

>>> import discoverhue
>>> found = discoverhue.find_bridges()
Problem at portal: HTTP Error 404: Not Found
Traceback (most recent call last):
  File "/home/sh/.local/lib/python3.7/site-packages/discoverhue/discoverhue.py", line 257, in find_bridges
    found_bridges.update(via_upnp())
  File "/home/sh/.local/lib/python3.7/site-packages/discoverhue/discoverhue.py", line 169, in via_upnp
    raise DiscoveryError('SSDP returned nothing')
discoverhue.discoverhue.DiscoveryError: SSDP returned nothing

During handling of the above exception, another exception occurred:

The hue bridge is running and working (with the iOS hue app), I can open the web interface and access the API info URL at https://hue/api/0/config (hue being the local DNS name, IP works as well).

Trying discovery with dns-sd works as per developer docs.

Anything I can/need to to from my side?

The bridge updated its firmware (forced by iOS app) on startup, not sure if this is relevant. Current API info is

{"name":"Philips hue","datastoreversion":"112","swversion":"1947108030","apiversion":"1.47.0","mac":"xxx","bridgeid":"xxx","factorynew":false,"replacesbridgeid":null,"modelid":"BSB002","starterkitid":""}

Oh, discoverhue is v1.0.2 (current install via pip3)
