Dear somebody,
I need some help. Wrote a component to synchronize play over multiple DLNA renderers.
When I attempt via install HACS I get a “Config flow could not be loaded: 500 Internal Server Error Server got itself in trouble” error.
I tried setting external URL in HA system but makes no difference. Tried solving this well into the morning hours.
Maybe I am missing something.
Any ideas?
Link to the component
