Still facing the same error:
[error] start_link “ws://localhost:3014/channel?channel_reserve=2&initiator_amount=7000000000000&initiator_id=ak_SVQ9RvinB2E8pio2kxtZqhRDwHEsmDAdQCQUhQHki5QyPxtMh&lock_period=10&minimum_depth=0&port=1564&protocol=json-rpc&push_amount=1&responder_amount=4000000000000&responder_id=ak_cFBreUSVWPEc3qSCYHfcy5yW2CWkbdrPkr9itgQfBw1Zdd6HV&role=responder”
I opened up the port this time while running my node 
@dimitar.chain: What could be the possible issue?
@dimitar.chain, if you think getting on a call and screen sharing might help better, I am happy to do that as well 
. I am Gyan0890#9895 at Discord.
Copy pasting the error here, once again:

Hi @gyan0890 please share some update here or in the bounty post so the general audience can know how things are working. Thanks!
Hi all,
As per my discussion with @dimitar.chain on Discord, I have changed the aeternity config file in my local running node to expose the webscoket at port 3014 and listen_address as “0.0.0.0” . PFA the latest config file. I have restarted the docker by applying this config file and now in the process of re-starting my channel service. Once the channl service is up and running(it takes about 6 hours or so on my machine), I will provide an update on the coin-toss-game.aeternity_config_schema.json (58.3 KB)
If anyone has any other suggestions, that would help to speed up the bounty, would be most happy to listen/implement
Quick update, even after changing the config file for websocket, same error persists:
[error] start_link “ws://localhost:3014/channel?channel_reserve=2&initiator_amount=7000000000000&initiator_id=ak_SVQ9RvinB2E8pio2kxtZqhRDwHEsmDAdQCQUhQHki5QyPxtMh&lock_period=10&minimum_depth=0&port=1564&protocol=json-rpc&push_amount=1&responder_amount=4000000000000&responder_id=ak_cFBreUSVWPEc3qSCYHfcy5yW2CWkbdrPkr9itgQfBw1Zdd6HV&role=responder”
Can you please provide the yaml config you’ve used
I added the .yaml file shown here: https://raw.githubusercontent.com/aeternity/ae-channel-service/master/test/aeternity_node_fast_test_config.yml
at /home/aeternity/.aeternity/aeternity inside my docker container. Re-starting my ae-channel-service now. Hope everything works for now. Will keep you updated here @dimitar.chain
Hi all, seems like the above error is finally solved (3014 one) after my steps as mentioned above. But here is a new error that I have come across:

To anyone interested in running the demo - you must:
127.0.0.1:3014, if you run a docker image - you must provide a proper setup to expose it out of the docker. Note that by default it is bound to the localhost of the docker image.ae-channel-service properly so it can sign your transactions for you. Sadly, the demo client does not do that so you must fill your key pair here. If you’re running a local standalone test, you must configure your accounts_test.json accordinglynetwork_id depending on the environmentAn example config files can be found in the ae-channel-service repo. There are two different setups, the difference between them is simply if the node mines with a normal speed or much faster. You can find the fast config here and the normal one here. Please note that if you want iris enabled, you shall add a corresponding line in the hard_forks section.
yeaahhh congratulations @gyan0890! And big thanks to @dimitar.chain for your great support!!! now is time to focus on getting the tutorial fully updated and checked for this scenarios so we can share everybody about statechannel knowledge.
I wish we could build something to make things understandable to rookies. Something with a simple UI like GitKraken that makes complicated things easy to understand:
@nikitafuchs.chain it would be as simple as providing a handful of settings to a docker image, it does not sound impossible…
@dimitar.chain @nikitafuchs.chain sounds like we could make some bounty of this. What do you think?
I need to wrap my head around that how this could look and feel like, anyone some rough suggestions ?
@nikitafuchs.chain: For the bigger picture, I have been thinking about something like this for Aeternity: Welcome to the course!
You can code while you learn. It is a very useful tool for developers to get easily on-boarded to anything while watching the videos - code while you learn kinda proceess.
You may have to Sign up to scrimba to view what I am talking about, but if anyone is game, I am happy to co-work to create something like this.
