I always get the message ‘Unable to start http server’ while I select the branch in Getting Started Tutorial. 
Log:

I’ve been getting this as well, but just ignoring it. The editor still seems to work fine for me.
If you get this message it will probably mean that you won’t be able to discover devices running dmengine and pushing content to them. Do you have multiple instances of Defold running? Maybe you have anti virus blocking? Or some other program blocking the port 8001?
work fine for you??
File, Save (Ctrl-S) - is not enabled
I can’t add new images into the project
You can’t add new images into the project? How exactly are you doing this? Could you please elaborate?

So I looked into my firewall settings and it seemed like defold and dmengine were both block on private network inbound. However when I changed blocked to enabled, I was still getting that error.

That’s weird everything else seems fully functional.
Drug and Drop works! 
Yes I have the firewall on my pc, however all your processes- defold.exe, dmengine and git-remote-http.exe have the status ‘Allow all’. Moreover I switched off the firewall at all, but no result. So I can’t realize which program blocks port 8001.
Netstat -an also doesn’t give an answer who blocks 8001
Ditto here. Stuck.
Start ->All Programs ->Accessories ->System Tools ->Resource Monitor
Go to Networking tab, expand Listening Ports. You can sort by port there to see what programs are using which ports.
