I am trying to run the Hypeledger Explorer for my blockchain network. I have followed the instructions almost word for word using the Hyperldger Explorer
But anytime I do the final call: ./start.sh --- I get a litany of errors
error: [client-utils.js]: sendPeersProposal - Promise is rejected: Error: 12 UNIMPLEMENTED: unknown service protos.Endorser

And so on. For more info I am using
nodejs 6.9 and PostgreSQL 9.5. This is the way my config.json file looks:

The problem is your hyperledger network does not have any endorser in network.
try first-network sample from official fabric-samples folder, rebuild the explorer and then try again.

I am trying to connect with Postgres 13 from loopback 4 but its showing error
Cannot migrate database schema Error: Timeout in connecting after 5000 ms
at Timeout._onTimeout (/Users/mohammad/Work/prithu/prithuPlatform/node_modules/loopback-datasource-juggler/lib/datasource.js:2654:10)
at listOnTimeout (internal/timers.js:554:17)
at processTimers (internal/timers.js:497:7)
I tried connecting with pgadmin and its connecting fine and I also tried connecting it with express and its also connecting. It was connecting with earlier system but after changing system and installing Postgres 13 it's not working.
Here is the snapshot of app-db.datasource.config.json
{
"name": "app_db",
"connector": "postgresql",
"debug": true,
"host": "localhost",
"port": 5432,
"user": "adminuser",
"password": "password123",
"database": "testdb",
"ssl": false
}
Finally I figured out what was the problem. It was because I was using node 14. There was no problem with the database. I then install the node 12 and it's working now.
I faced the same issue.
I was putting the wrong password for postgres user in datasource.config, check that.
{
"name": "app_db",
"connector": "postgresql",
"debug": true,
"host": "localhost",
"port": 5432,
"user": "adminuser",
"password": "password123", (maybe this password is wrong)
"database": "testdb",
"ssl": false
}
I am trying to deploy Strapi on a Dokku instance on a Digital Ocean droplet. I originally ran into some issues connecting to the mongo database, but after some trial and error and a lot of review of these docs and this issue, I was able to get it to stop complaining about the mongo connection. Here was my final config/environments/production/database.json
{
"defaultConnection": "default",
"connections": {
"default": {
"connector": "mongoose",
"settings": {
"client": "mongo",
"uri": "${process.env.MONGO_URL}",
"database": "${process.env.DATABASE_NAME}",
"username": "${process.env.DATABASE_USERNAME}",
"password": "${process.env.DATABASE_PASSWORD}",
"port": "${process.env.DATABASE_PORT || 27017}"
},
"options": {
"authenticationDatabase": "${process.env.DATABASE_AUTHENTICATION_DATABASE || ''}",
"useUnifiedTopology": "${process.env.USE_UNIFIED_TOPOLOGY || false}",
"ssl": "${process.env.DATABASE_SSL || false}"
}
}
}
}
Here is my config/environments/production/server.json
{
"host": "${process.env.HOST || '0.0.0.0'}",
"port": "${process.env.PORT || 1337}",
"production": true,
"proxy": {
"enabled": false
},
"cron": {
"enabled": false
},
"admin": {
"autoOpen": false
}
}
I believe the original issue was that I was accidentally using the PORT variable for the database instead of the DATABASE_PORT variable.
However, now that I have that worked out I am getting this error:
error Error: listen EADDRNOTAVAIL: address not available <my-host-ip>:5000
I thought maybe there was some wrong port being cached somewhere, but regardless of what I do, I can't seem to get it to work. Do I need to enable ssl? and then add a letsencrypt cert to my domain? am i using the wrong ports? set a proxy in the server.json?
PS. I am using Dokku Mongo. Didn't think that would be an issue considering the dynos don't go to sleep like they would on heroku. Is that an incorrect assumption?
Also, there are other apps running on the droplet. Maybe a proxy problem?
I'm writting a micro service with spring-boot. The db is mongodb. The service works perfectly in my local environment. But after I deployed it to the cloud foundry it doesn't work. The reason is connecting mongodb time out.
I think the root cause is the application doesn't know it is running on cloud. Because it still connecting 127.0.0.1:27017, but not the redirected port.
How could it know it is running on cloud? Thank you!
EDIT:
There is a mongodb instance bound to the service. And when I checked the environment information, I got following info:

}
}
From my understanding, I think my spring-boot service should try to connect the port 43417 but not 27017, right? Thank you!
Finally I found the reason is I didn't specify the profile. After adding following code in my manifest.yml it works:
env:
SPRING_PROFILES_ACTIVE: cloud
Using Hyperledger Composer v0.7.4 (on Ubuntu 16.04) I have tried deploying a business network to a HSBN in Bluemix, but I get the following error:

Had a friend try it on a Mac on my same business network with the same connection profile and it worked. Tried reinstalling everything (even reinstalled Ubuntu) and still no luck.

Any idea why I'm getting this error?
Solved it by setting my DNS to 8.8.8.8
Take a look at this question How do I set my DNS when resolv.conf is being overwritten?
Recently I build presto with cluster mode, 1 coordinator & 1 worker, it works.
Then I repackage "presto-main-0.148.jar" without any change , and replace it to production environment, it doesn't work! Always get response with "No worker nodes available"
I search the Server.log and see below messages:
ERROR Discovery-0 io.airlift.discovery.client.CachingServiceSelector Cannot
connect to discovery server for refresh (collector/general): Lookup

ht*p://10.3.2.33:18080/v1/service/collector/general
ERROR Discovery-0 io.airlift.discovery.client.CachingServiceSelector Cannot

INFO Discovery-1 io.airlift.discovery.client.CachingServiceSelector Discovery
server connect succeeded for refresh (collector/general)
INFO Discovery-2 io.airlift.discovery.client.CachingServiceSelector Discovery
server connect succeeded for refresh (presto/general)
So I guess discover server is not started,But I use command curl "h*tp://10.3.2.33:18080/v1/service/collector/general",
and get response below, and I also get coordinator status as 'ACTIVE'

I think this is because that you have two different node_version in these two services.
If you are repackaging presto-main or any other component, make sure you are using the same binaries on all the nodes.
