Issue with not being able to detect devices. (pairdrop image)

most of the context can be seen here. [BUG] devices do not show up in pairdrop · Issue #16 · linuxserver/docker-pairdrop · GitHub
Im using the default docker compose file provided in the readme of the pairdrop image.
My windows laptop and android phone are unable to see each other on the same wifi network. Ive tried putting them in the same room, and pairing them with each other. they do not work. although on my phone i was able to see a choice for my phone when there is another pairdrop tab open.
