"return status Download and verify bundle failed with msg: stopped the pause stream!" while upgrading NSX-T edge node

Products

• VMware NSX

Issue/Introduction

• Upgrading from NSX-T 3.2.x to NSX 4.2.x.
• In the NSX UI the edge upgrade fails with error:

Prepare edge upgrade bundle http://<Manager-IP>:8080/repository/4.2.1.3.0.24533884/Edge/nub/VMware-NSX-edge-4.2.1.3.0.24533894.nub failed on edge TransportNode 1342540d-####-####-####-92e5a596a201: clientType EDGE , target edge fabric node id 1342540d-####-####-####-92e5a596a201, return status Download and verify bundle failed with msg: stopped the pause stream! .

• In the NSX-T Edge /var/log/syslog the following log entry is seen:

NSX 1105 - [nsx@6876 comp="nsx-edge" subcomp="upgrade-agent" tid="1474" level="ERROR" errorCode="MPA50007"] Error downloading nub 'http://<Manager-IP>/repository/4.2.1.3.0.24533884/Edge/nub/VMware-NSX-edge-4.2.1.3.0.24533894.nub', output msg: , error msg: *   Trying <Manager-IP>...#012* TCP_NODELAY set#012* Connected to <Manager-IP> (<Manager-IP>) port 8080 (#0)#012> GET /repository/4.2.1.3.0.24533884/Edge/nub/VMware-NSX-edge-4.2.1.3.0.24533894.nub HTTP/1.1#015#012> Host: <Manager-IP>:8080#015#012> User-Agent: curl/7.58.0#015#012> Accept: */*#015#012> #015#012< HTTP/1.1 200 OK#015#012< Content-Type: application/octet-stream#015#012< Accept-Ranges: bytes#015#012< Content-Length: 34099200#015#012< Date: Sat, 27 Sep 2025 10:19:38 GMT#015#012< Server:  #015#012< #015#012{ [10065 bytes data]#012* Failed writing body (0 != 10065)#012* stopped the pause stream!#012* Closing connection 0#012

• Prior edges/edge cluster may have upgraded successfully.
• Port 8080 is open from the edge to the manger as tested with:

nc -zv <<Manager-IP> 8080

• Running wget to the manager pulls down the nub file: 

wget <Manager-IP>/repository/4.2.1.3.0.24533884/Edge/nub/VMware-NSX-edge-4.2.1.3.0.24533894.nub

• Forward and back DNS resolution of the manager IP and FQDN from the edge node works, check as root user:

nslookup <Manager IP>

nslookup <Manager FQDN>

• Reboot of the edge and manager does not resolve the issue.

Note: Port 8080 is required for the 3.x NSX versions, NSX 4.x requires port 443, therefore port 8080 is required during the upgrade: VMware Ports and Protocols

Environment

VMware NSX

Resolution

The edge node may have some corrupt partition(s), perhaps due to a previous storage issue.

Workaround:

Replace the failed edge node and retry the upgrade: Replace an NSX Edge Transport Node Using the NSX Manager UI
