Does anyone knows how to fix this?

Process terminated. Fatal error detected: RabbitMQ.Client.Exceptions.BrokerUnreachableException: None of the specified endpoints were reachable
RabbitMQ.Client.Exceptions.OperationInterruptedException: The AMQP operation was interrupted: AMQP close-reason, initiated by Library, code=541, text='Unexpected Exception', cla...

rabbitmq log:
{handshake_error,opening,0, {amqp_error,access_refused, "access to vhost '/hostname' refused for user 'admin2'", 'connection.open'}}
tell me what can be done?
I made trough the rabbitmq web interface new vhost and user, made an access to the vhost, did not help

Oracle SQL Developer Status Error Failure -Test failed: IO Error: The Network Adapter could not establish the connection on linux (Ubuntu)

I recently switched to ubuntu and when I installed and tried to create a connection on Oracle SQL Developers 22.2.1 I get a error
Status : Failure -Test failed: IO Error: The Network Adapter could not establish the connection
Ive tried changing the ports and switching between JDK 19,17 and 11 non of them seem to fix the error, all the guides that i can find on this error seem to be specifically for windows.
any help is appreciated and apologies if I have couldnt explain my problem clearly.

i got this error when i am trying to connect peers running in different machines .I found this error in docker logs of orderer.There is an error in docker logs of peer2 running in different machine

You can find the orderer.yaml file at fabric-samples/config folder.
Going through the fields and their respective comments in orderer.yaml and core.yaml can help you to understand the method of configuring the network(orderer/peer).

Chef-server-ctl reconfigure/ Creating Admin User on chef server

I am fairly new to Linux (and brand new to chef) and I have ran into an issue when setting up my chef server. I am trying to create an admin user with the command
sudo chef-server-ctl user-create admin Admin Ladmin admin#example.com
examplepass -f admin.pem
but after I keep getting this error:
ERROR: Connection refused connecting...
ERROR: Connection refused connecting to https://127.0.0.1/users/, retry 5/5
ERROR: Network Error: Connection refused - Connection refused
connecting to https://..., giving up
Check your knife configuration and network settings
I also noticed that when I ran chef-server-ctl I got this output:
[2016-12-21T13:24:59-05:00] ERROR: Running exception handlers Running

[2016-12-21T13:24:59-05:00] ERROR: Exception

I read that this error is due to a prerequisite mistake but I'm uncertain as to what it means or how to fix it. So any input would be greatly appreciated.
Your server does not have a valid FQDN (aka full host name). You'll have to fix this before installing Chef server.

Parse Server + Express - Issues with ParseError and site dying/restarting

I have deployed a Bitnami Parse stack to a Google Cloud VM. This stack is basically Apache running as a proxy, Then a MEAN stack handling parse server and dashboard etc.
Everything appears to be working fine when accessing the dashboard and sending individual CURL requests to test it's all available.
However, there appears to be a fatal flaw in that. When Parse returns one of it's errors e.g.
{"code":101,"error":"Object not found."}
Express sees it as an uncaught exception and dies. Now I realise that it's intentional behaviour (There's enough information out there as to why you don't want to persist after an uncaught exception)
The Bitnami stack uses Forever to run the Parse Server, but as you can see from the logs I will include below, you still run into issues with refused connections.
2016-11-25T11:41:16+00:00 DEBUG (7): {"code":101,"error":"Object not found."}
2016-11-25T11:41:16+00:00 DEBUG (7): Failed to connect to X.X.X.X: Connection refused
2016-11-25T11:41:17+00:00 DEBUG (7): Failed to connect to X.X.X.X: Connection refused
2016-11-25T11:41:17+00:00 DEBUG (7): Failed to connect to X.X.X.X: Connection refused
2016-11-25T11:41:17+00:00 DEBUG (7): Failed to connect to X.X.X.X: Connection refused
Meanwhile in the Forever logs:
Error generating response. ParseError { code: 101, message: 'Object not found.' } code=101, message=Object not found.
[object Object]
/opt/bitnami/apps/parse/htdocs/node_modules/parse-server/lib/ParseServer.js:425
throw err;
^
Error: EACCES: permission denied, open '/opt/bitnami/apps/parse/htdocs/logs/parse-server.info.2016-11-25'
at Error (native)
error: Forever detected script exited with code: 7
error: Script restart attempt #1
parse-server running on port 1337
parse-dashboard running on port 4040
So you can see that immediately following a Parse error being returned, The service is unavailable until Forever can restart the Parse Server.
This issue appears that it would affect all users as well, so if one user receives an exception, all users lose connection for a brief period.
So the question is, how should this be properly handled? Is Parse + Express not the way to go about it? Or is there some method of configuring Node or Express to return the API error to the requester, without Express dying (And without having to fall into the trap of using uncaughtException to keep Node alive)
Any help would be much appreciated, thank you
The logs from Forever said it's EACCES error, that means ParseServer couldn't access the log file and not able to write the info log in it.
Error: EACCES: permission denied, open '/opt/bitnami/apps/parse/htdocs/logs/parse-server.info.2016-11-25'
at Error (native)
error: Forever detected script exited with code: 7
error: Script restart attempt #1
parse-server running on port 1337
parse-dashboard running on port 4040
I think you have to change the /opt/bitnami/apps/parse/htdocs/logs with proper permission so that ParseServer can write log files in it.
