NSX Preparing for upgrade shows Management service is not available. Connect to #.#.#.#:443 failed: Connection timed out

2024-11-03T09:20:44.418Z ERROR task-executor-6 ManagerDeploymentResolver 15936 SYSTEM [nsx@6876 comp="global-manager" errorCode="MP26044" level="ERROR" subcomp="manager"] Repair failed for MP appliance VM b######2-7##a-1##2-2###-02########c9.

 

org.springframework.web.client.ResourceAccessException: I/O error on POST request for "https://#.#.#.#:443/api/v1/cluster/node": Connect to #.#.#.#:443 [/#.#.#.#] failed: Connection timed out (Connection timed out);

 

nested exception is org.apache.http.conn.HttpHostConnectException: Connect to #.#.#.#:443 [/#.#.#.#] failed: Connection timed out (Connection timed out)

 

netcat to local host over port 443 will be successful

# nc -z -v localhost 443

  Connection to localhost 443 port [tcp/https] succeeded!

 

But will time out when attempting to connect to any other manager over 443:

# nc -z -v #.#.#.# 443

nc: connect to #.#.#.# port 443 (tcp) failed: Connection timed out

 

repo_sync status will show as failed. Attempting to resolve doesn't help and remains in the same status.

 

Environment

VMware NSX

Resolution

Workaround

1.  Restart the proxy service on affected Manager

     /etc/init.d/proxy restart
