Our code is failing to get connected to resources on the GroupShare server using FileBasedProject to build automations.  The implementation is using a language pair specific template to configure use of TMs and the SDL MT Cloud plugin.  During Analyze and Pre-Translate tasks, we are getting the following error:
"Unexpected exception when initializing task 'Analyze Files': Failed to create an instance of translation provider 'sdltm.server.domain.com/ - German'.."

The same template and processing flow have been working on Studio2019 with GroupShare 2017, but are now failing when upgrading to Studio 2021.

Language pair section of the template:
