It might be your neo4j was still running.
I solved this problem by shutting down the database and restarting it.
Platform: Windows 10;
Neo4j Desktop version: 1.1.13
Open a commend-line window and go to the directory of your neo4j database.
run
bin\neo4j status
to check the status of your database.
If it is running, run
bin\neo4j stop
to shut down your database.
Then go back to the Neo4j Desktop, click the start button, and it could be symptom-free.
I had the same problem and the issue was resolved when I cloned the graph I was connecting. Thereafter, I could connect to the new graph without any problem.

I just started to learn solr with official documentation and during the first exercise "Index Techproducts Example Data" I failed due to following error: " Failed to create collection 'techproducts' due to: Underlying core creation failed while creating collection: techproducts".
I tried to change java version from 13 to 8 but it didn't helped.
Here is link to the documentation: https://lucene.apache.org/solr/guide/8_5/solr-tutorial.html#exercise-1
Stacktrace from solr Admin console

I had run into similar situation while following Solr
's official tutorial as following
➜ solr-8.7.0 ERROR: Failed to create collection 'techproducts' due to: Underlying core creation failed while creating collection: techproducts
And problem solved my turning off my vpn. I guess the vpn routing probably messed up with solr's localhost setting somehow.
I had the same Underlying core creation failed... error too. Using Java 11, Windows 10.
The log file was ${solr-home}\example\cloud\node1\logs\solr.log. Inside it had:
org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException: Error from server at http://192.168.1.16:7574/solr: Error CREATEing SolrCore 'techproducts_shard1_replica_n1': Unable to create core [techproducts_shard1_replica_n1] Caused by: no segments* file found in LockValidatingDirectoryWrapper(NRTCachingDirectory(MMapDirectory#{solr_home}\example\cloud\node2\solr\techproducts_shard1_replica_n1\data\index lockFactory=org.apache.lucene.store.NativeFSLockFactory#16326253; maxCacheMB=48.0 maxMergeSizeMB=4.0)): files: [write.lock] at org.apache.solr.client.solrj.impl.HttpSolrClient.executeMethod(HttpSolrClient.java:681) ~[?:?]

But this was the second time I launched solr. The first time it timed out trying to contact one of the nodes and the tutorial script aborted. But the nodes were still running. I killed them off using the windows task manager and not by using solr stop. So I suspect I left an instable mess behind and the second time the tutorial ran it crashed into this mess.
I erased everything and started over from unzipping and this third time there were no timeouts and the tutorial completed without error.
File: /opt/solr/server/etc/jetty.xml
(1) Name="requestHeaderSize" set Property name "solr.jetty.request.header.size" default="81920"
(2) Name="responseHeaderSize"> set Property name="solr.jetty.response.header.size" default="81920"
(3) Restart Solr
Hm, tried this, still getting the exact same error.
After Change:
[Set name="requestHeaderSize"][Property name="solr.jetty.request.header.size" default="81920" /][/Set]
[Set name="responseHeaderSize"][Property name="solr.jetty.response.header.size" default="81920" /][/Set]
I stopped everything and retried, then I had Windows Firewall prompt me for 'SAP Machine' authorization for java 11 message, I accepted it, and retried. Then it worked. Seems Windows Firewall related.
SQL server syspolicy_purge_history job step 3 failed due to below error. Is any one faced same kind of issue while run this step#3?

I am trying to run the QuickStart2_ResourceOwnerPasswords sample. I could view the http://localhost:5000/.well-known/openid-configuration without issues. However when I run the Client.dll from the console it gives me following error:
Unhandled Exception: System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.Http.WinHttpException: A connection with the server could not be established
at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()
at System.Threading.Tasks.RendezvousAwaitable`1.GetResult()
at System.Net.Http.WinHttpHandler.<StartRequest>d__105.MoveNext()
Any help is appreciated!
Note: I am running the QuickStartIdentityServer as start up project (this runs the Identity Server implementation in the background with command window showing logs). I am currently running the Client.dll from a separate window using the command:
dotnet Client.dll
Not sure if this is the correct way of testing it...
I just finished building my app and I sent a build with no certificate and it worked...now on adding an android certificate, it reports a build error on my codename one dashboard. A help will be appreciated.
FAILURE: Build failed with an exception. * What went wrong: Execution
failed for task '
:transformClassesAndResourcesWithProguardForRelease'. >
java.io.IOException: Please correct the above warnings first.
Warning: Exception while processing task java.io.IOException: Please correct the above warnings first.

I will need the full error as that point is already too low. I recall seeing some failures when punctuation was used in one of the certificate properties as Android chokes on that. It should appear in the error logs.
On Development Server, whenever I add an taskqueue
taskqueue.add(queue_name='default', url='/_tasks/do_something', params={'key': 1})
The following error occurred
taskqueue_stub.py:1974] Task task1 failed to execute. This task will retry in 819.200 seconds
After getting some hint from this post:
http://www.rogerthat.net/2012/03/27/google-app-engine-push-task-queues-the-development-environment/
I suspect it could be something to do with the hostname. I am using http://test.me:8088 (where test.me point to 127.0.0.1 using host file). The problem goes away when I change the hostname (test.me) to "localhost".
I can't just use localhost due to some app configuration issue.
The code edit rogerthat.net point out is no longer valid.
Any other solution?
