composer-playground EACCES error when lauching - hyperledger-composer

When I'm trying to start composer-playground from ubuntu I got the error:
$ composer-playground info: [Hyperledger-Composer] :LoadModule
:loadModule() Loading composer-wallet-filesystem from
/home/rui.oliveira/.nvm/versions/node/v8.11.3/lib/node_modules/composer-playground/node_modules/composer-wallet-filesystem
info: [Hyperledger-Composer] :PlaygroundAPI :createServer()
Playground API started on port 8080 events.js:183
throw er; // Unhandled 'error' event
^
Error: EACCES: permission denied, open '/home/...log'
When I go to the log file the only entry I've got is:
2018-09-21T20:38:52.508Z ERROR :HLFConnectionManager
:fabric-client() [ChannelEventHub.js]: _connect - timed out
after:300000 {}$
My current log level is: composer[debug]:*
I'm using REST Server with oauth and multi-user and I can do GET or POST with success (HTTP200) but when I do a POST transaction nothing is set to the peers.
Can someone help trying to debug this?
EACCES is permission denied but not sure what is really being denied here...
Thanks in advance.

: API error (404): network hlfv11_hyperledger not found

✖ Starting business network definition. This may take a minute...
Error: Error trying to start business network. Error: No valid responses from any peers.
Response from attempted peer comms was an error: Error: failed to execute transaction b5c260c02b4792c4ae4b85b3d4ccb4565a495da399d27917dccc1a84244e631f: error starting container: error starting container: API error (404): network hlfv11_hyperledger not found

This looks like it is a Docker problem trying to start a new ChainCode container on a Docker Network bridge called "hlfv11_hyperledger" which doesn't exist.
(The word 'network' here is ambiguous in the error message :-( )
This is the same problem and hopefully the same solution as a previous post.

Vertica admintools error

when I try to connect to database from admintools I am getting following error:
Error: Unable to connect to database
Hint: Username or password could be invalid
I have found in the logs following error:
Apr 20 08:08:29 [24291] [vsql.connect spawn] Exception: Error! pty.fork() failed: out of pty devices
Do you know what is the problem?
Your node might be down
Check logs at
/opt/vertica/log
or at
/opt/vertica/config/admintools.conf
check restart policy section is right
[Database:mydb] host = 11.11.11.11
restartpolicy = ksafe

You're getting an access denied error upon attempt to start network service. Your permissions are probably restricted.

I'm running a shell script before I try to run a local copy of my meteor app. It supposed to stop my application from interacting with other APIs. When I run the script (I'm on a mac) through my terminal, it returns '0' which as I read means that there are zero errors. I know that the error message is guiding me to certain lines of code, but I don't understand why I would change them if my co-worker could get his copy up and running. He is running his application on a windows computer. Thank you. I'm pretty new to this.
It was a permission error just as #thatgibbyguy first suggested. I was able to run it buy using sudo meteor to override the permission restrictions. I wasn't about to remove my mongod.lock file since that my coworker had the file and was able to get it up and running.
