groov native OPC UA server does not accept connections to localhost


Applies To:

Firmware for the following groov EPICs:

  • GRV-EPIC-PR1
  • GRV-EPIC-PR2

Versions Affected:

3.4.0

Resolved In Version:

3.4.1


Symptoms:

In your OPC UA client, if you specify localhost as the connection string to connect to the groov EPIC native OPC UA server, when you try to browse for tags, you get error messages. For example, in groov View, if you specify localhost:14840/groov as the connection string, you get the "OPC-UA Service Error" message.

Workaround:

Change the localhost part of the connection string to localhost.localdomain. For example, in groov View, change localhost:14840/groov to localhost.localdomain:14840/groov.

Resolution:

Opto 22 has resolved this issue.
