How to reconnect to Neo4j in Grails

Hi,
I'm trying to using neo4j in Grails , however when I configured the neo4j db connection in the groovy config (Attached Below) , the neo4j db crashed in very short time and recovered soon, but my service will not reconnect to neo4j db unless I restarts the service.
Is there a solution that we can auto reconnect to neo4j that we do not need to restart the service again?

Have you encountered similar problems related?What's the solution?
Thank you very much!

environments {
development {
perEnvironmentDomain="-dev.$gtlcOnlyDomain"
apiRoots()
apis()
grails {
// neo4j datasource
neo4j {
url="bolt://cm-graphdb"
username='neo4jUser'
password='neo4jPassword'
}

Hi
Please check the bolt url.
I think there is some problem with bolt url.
Thanking you
