Can connect from PC to MAC but not Mac to PC

I can run crowdrender on my PC and render from my Macbook (using macbook as the render slave) and connect to my mac no problem.

When running Blender on my Macbook, I can't see my PC nor can I connect manually. This is a problem since I want to work on my laptop and render with my PC. Any advice?

Same here; Win to Mac as Slave works, Mac to Win(as slave) not working; cloud rendering panel helps so that they find each other, still connection is not working

Hi David, any details you could provide would really help :) Such as;

All Versions of blender + crowdrender you're running on both machines
Any error messages?, there are logs capture on both machines in the user\cr\logging folder
Are you running a firewall on the windows machine, if so does it allow blender to listen on any TCP ports?
If you know how, would be handy to check if the windows machine is running any other processes that are listening or connected to TCP ports in the range 9000-9025, if there are, or you suspect there might be, you can try moving crowdrender to a different port range by going to blender > preferences > addons > crowdrender > expand the addon and go to the 'networking' section and then select a new port number for the 'start port'. I'd recommend trying 9669 for this value.

Regarding 2, if you want to send us logs, please upload them with a support ticket at https://www.crowd-render.com/report-a-problem :)

I'm having a similar issue. My render nodes are PCs, but my work machine is a mac. I can get them to connect fine, but they fail to sync. I should also mention that when I try to sync mac to mac, I can sync fine. It's just when I use Mac as the master, and my render nodes which are PCs, I can't sync. I can connect fine though.

Hi James,

Hope you are well. As you might imagine, we need a bit more information than this to figure out what might be causing the problem! But to help you self diagnose, here are a few things.

1. You can connect from the PC to the mac, so it seems that the connection works one way, does the PC have a firewall running? If so did you allow blender to accept incoming connections in windows' firewall or are you running any anti virus software that might be stopping an incoming connection from the mac? Best way to decide this is to turn off the anti-virus and firewall temporarily and see if the problem goes away.

2. Have you tried restarting both the mac and PC? Sometimes a background service we use can hang and the computer might not be able to receive incoming connections, or the mac as a client might not be able to make connections out to the PC.

3. Consider sending us the logs from both computers, any errors in connection or setup might show up there.

Hope this helps :)
