Unable to connect to seed node - digital ocean / firewall problem

+2 votes
I started with one digital ocean droplet with a multichain chain as per the tutorial. I was then unable to connect to it from the linux box in my house, receiving an error on my command. This shown with debug parameters.

multichaind chain1@107.170.205.233:7203 -debug=mchn -debug=mchnminor -debug=net

 

MultiChain Core Daemon build 1.0 alpha 26 protocol 10006

Error: Couldn't connect to the seed node 107.170.205.233 on port 7203 - please check multichaind is running at that address and that your firewall settings allow incoming connections.

I messed with this for an hour. No dice. NEXT: I decided that maybe it would be easier to remove variables. I set up a second droplet on digital ocean (both in SF1 data center), and set up private networking. I tried to connect the second node to the first...

Any advice is appreciated.

********* UPDATE:

I downgraded to alpha 25, and the problem went away.

Thanks for this report. Do you still have the debug.log file relating to the failed connection attempt when you ran multichaind with the -debug flags, from the node which tried to connect?
