Hi Guys,
Need urgent support on this . We have NSX version 6.3.2 . I am getting a strange error " connection refused" on a load Balancer pool.
POOL f9-apo-34-23886
| LB METHOD leastconn
| LB PROTOCOL L7
| Transparent disabled
| SESSION (cur, max, total) = (0, 1, 8)
| BYTES in = (0), out = (0)
+->POOL MEMBER: f9-apo-34-23886/F9POUCMAP100, STATUS: DOWN
| | HEALTH MONITOR = BUILT-IN, default_tcp_monitor:L4CON
| | | LAST STATE CHANGE: 2019-02-28 09:42:46
| | | FAILURE DETAIL: Connection refused
| | SESSION (cur, max, total) = (0, 0, 0)
| | BYTES in = (0), out = (0)
For the same member , Other pool is UP
POOL f9-apo-34-23877 |
| LB METHOD leastconn |
| LB PROTOCOL L7 |
| Transparent disabled |
| SESSION (cur, max, total) = (0, 45, 26405) |
| BYTES in = (25137834694), out = (4198502549) |
+->POOL MEMBER: f9-apo-34-23877/F9POUCMAP100, STATUS: UP |
| | HEALTH MONITOR = BUILT-IN, default_tcp_monitor:L4OK |
| | | LAST STATE CHANGE: 2019-02-28 06:55:53 |
| | SESSION (cur, max, total) = (0, 45, 26105) |
| | BYTES in = (25137825550), out = (4198502549) |
***NOTE : They have the same pool member F9POUCMAP100
Port is open from server end . There is no firewall in between as well. How can we troubleshoot the same . PLease guide me on the same .
From NSX trouble shooting guide
L4OK: Check passed on layer 4, no upper layers testing enabled
L4CON: Layer 1-4 connection problem. For example, "Connection refused" (tcp rst) or "No route to host" (icmp)
I Have also checked L3 connectivity . All looks good. I am able to ping pool Member.
