SLNet – DMA cannot connect to the cluster due to error in creating the Web Proxy

Hi Dojo,

I’m experiencing an issue where one DMA cannot connect with the rest of the cluster, though the cluster can connect with the agent. For example:

  • When I connect to the problematic agent, I see all other DMAs as disconnected, unknown, or refused.
  • However, when connecting to another agent in the cluster, this problematic DMA appears as connected.

After reviewing the SLNet logs, I found the following error:
Error creating the Web Proxy specified in the 'system.net/defaultProxy' configuration section.

Upon inspecting the SLNet.exe.config file, I noticed a potential issue with parsing the * wildcard in the configuration:

<system.net>
<connectionManagement>
<add address="*" maxconnection="200" />
</connectionManagement>
<defaultProxy>
<proxy proxyaddress="http://xxxxxxx:8080" bypassonlocal="true" />
<bypasslist>
<add address="*.xxx.xxx.xxx" />
</bypasslist>
</defaultProxy>
</system.net>

The other DMAs in the cluster do not have a bypasslist configured.

My question is:
Is there any flow or mechanism within DataMiner that could configure or modify the bypasslist in the SLNet configuration?

Hi Catarina,

The SLNet.exe.config file is usually updated during a DataMiner upgrade. The modified tags can differ between versions to meet DataMiner's requirements.
Otherwise, I'm only aware of manual modifications.
