Roon skips every track when casting to chromecast

Whenever I try to cast to a chromecast (I have 2 and get same behavior on both) it just skips past all of the tracks and won’t play anything. I checked the log and get a few lines of errors seen below
“”, “payloadUtf8”: “{“requestId”:290,“type”:“INVALID_REQUEST”,“reason”:“INVALID_MEDIA_SESSION_ID”}” }
02/05 18:59:01 Warn: [zone Family Room TV] Track Stopped Due to Error

I am running roon server on a windows server 2016 VM. I did have to open some ports on the windows firewall to get everything working. I can’t remember if it was for roon arc and regular roon or just roon arc but I had to find the ports to open in a random post on here i believe. I am wondering if I need to do the same for chromecast devices. I can provide more of the log if needed.

@donfrenchiano, do you have the same issue if you try casting to either Chromecast from a Chrome browser in your Windows VM? If so, then it may indicate a network issue and something not specific to your Roon Core.

@Robert_F I can cast from chrome from the VM fine. This seems specific to roon/chromecast

So I was able to get this working. I had to make an outgoing firewall rule windows to open tcp ports 8008 and 8009.

Interesting fix Daryl, glad you are running again. How did you decide on these ports?

This post specifically mentions these ports for Chromecast.
