SnapCenter 6.0 - proxy issue

kombayn — Tue, 13 Aug 2024 12:28:56 GMT

Hello

I've upgraded SnapCenter from version 5.0 to 6.0 and since upgrade ALL jobs are failing with below error:

Error: The proxy tunnel request to proxy 'http://x.x.x.x:3128/' failed with status code '403'."

The fun fact is that I've never used proxy for SnapCenter and I've even noticed that I have the same proxy error for migrating SnapCenter repository backup schedule which is local on SnapCenter host:

I've tried to search where could the proxy settings be configured - in the appsettings.json there is nothing - I only found this:
"ProxyTo": ""

Does anyone knows where the proxy settings could be located? And why they changed after upgrade?

Hello,

Have you try the 6.0P1 version ?

And have you IPv6 enable on your SnapCneter ? if yes try to disable it

Hello. From what I can see on support site there is no P1 version available yet for SnapCenter server - only vSphere plugin has P1. I've disabled IPv6 and rebooted the host but it didn't resolve the issue.

Hello Kombayn,
have you found the proxy-settings of SnapCenter 6?
We have problems with the usage of our proxy, also.

Hello. We have a case opened with Netapp support for quite a long time and we're working to find a solution. For the moment the root cause is still not known.

Hello

We can try some possible options to avoid the use of the proxy:

A.- Remove a proxy server from the snapcenter host using the netsh command:

Open admin cmd prompt on the SnapCenter host
Type netsh winhttp reset proxy and press Enter
The result will have the following output:

Current WinHTTP proxy settings:
Direct access (no proxy server)

Restart the Snapcenter server

B.- Remove the proxy from Internet Options

Go to Start > Control Panel > Internet Options > Connections tab Click LAN Settings button
Un-check all boxes under Automatic Configuration
Un-check the box under Proxy Server
Click OK

C.- Disable system proxy via SnapCenter configuration file

Edit: %ProgramFiles%\SMCore\SMCoreServiceHost.dll.config file (consider making a copy of the file before doing the changes below)
Between <system.net> and </system.net> add the following text:
