    Description

      Description:

      Seeing warnings like

      [WARN ] 2020-06-18 07:09:51.328 [cb-events] endpoint - [com.couchbase.endpoint][EndpointConnectionFailedEvent][108us] Connect attempt 257 failed because of UnknownHostException: fd63:6f75:6368:20d4:423d:37c3:e6f7:3fac:: invalid IPv6 address {"bucket":"lCx_lsQL3OcVNj","circuitBreaker":"DISABLED","coreId":"0x7072a90f0000000e","remote":"fd63:6f75:6368:20d4:423d:37c3:e6f7:3fac::11210","type":"KV"}
      		 
      java.net.UnknownHostException: fd63:6f75:6368:20d4:423d:37c3:e6f7:3fac:: invalid IPv6 address

       when trying to connect to a ipv6 node with its ip address [fd63:6f75:6368:20d4:423d:37c3:e6f7:3fac]

      Script to Repo:

      /testrunner -i /tmp/durability_volume.ini sdk_client_pool=True,rerun=False,log_level=debug,installParameters=enable_ipv6=True,bucket_spec=single_bucket.def_scope_fifty_collections -t bucket_collections.basic_ops.BasicOps.test_delete_default_collection,nodes_init=1,client_type=sdk

      we see the above warning and ultimately see after certain number of retries:

      [DEBUG] 2020-06-18 07:09:51.335 [cb-events] request - [com.couchbase.request][RequestNotRetriedEvent] Request CarrierBucketConfigRequest not retried per RetryStrategy (Reason: NODE_NOT_AVAILABLE) {"cancelled":true,"completed":true,"coreId":"0x7072a90f0000001a","idempotent":true,"reason":"NO_MORE_RETRIES (NODE_NOT_AVAILABLE)","requestId":37431,"requestType":"CarrierBucketConfigRequest","retried":0,"service":{"bucket":"lCx_lsQL3OcVNj","collection":"_default","opaque":"0xb270","scope":"_default","target":"fd63:6f75:6368:20d4:423d:37c3:e6f7:3fac:","type":"kv"},"timeoutMs":2500}

      Have attached the log with sdk debug enabled.

      I was able to reproduce the warning with the standalone script (java client 3.0.5) HelloWorld.java

      Sometimes here with this script it does connect(with or without retries), sometimes it doesn't.

      with the hostname given instead of Ipv6 address, it always works fine - ie;

      Cluster.connect("s10505-ip6.qe.couchbase.com", "Administrator", "password");
