after Update to GS: 14.0.5111.4: can't update Server TM via Studio automation

Hello Language Developers

We have developed an automation with Studio 2017 API that can process return packages and update the server TMs of a customer using GroupShare. All worked well until the customer updated to GS 14.0.5111.4.

The automation can log in to the TM Server using the specified credentials. Access rights include the right to import.

But we get this error:

Unexpected exception when configuring file multiFileConverter for task 'Update Main Translation Memories': Failed to create an instance of translation provider 'sdltm.https://xxxxxx:111/?orgPath=/&tmName=zzzz_de-DE_ru-RU'

Studio 2017 Version is 14.0.5889.5 (can this be the main reason for the error?)

 

Is this problem known to you? Do you have an explanation  and/or a solution to our problem?

Any help is very well appreciated.

Than you in advance
