DeepL Translation Provider - version 4.8.22.1 - Trados Studio 2019 - Proxy Authentication Required issue

We have installed the latest version of the DeepL plugin 4.8.22.1

When we tried to use it last week, we got the following error message "There was a connection protocol error. Please check that you have entered the correct port number and other settings". The details of the error message reads "The remote server returned en error (407) Proxy Authentication Required."

See the attached log and screenshots for details.

After talking with our network engineers, we got confirmation first that deepl.com domains are whitelisted, second that this version of the DeepL plugin seems to fail authenticating to our Proxy.

In order to resolve the issue temporarily, a rule has been set to allow the DeepL plugin work without authenticating.

I would appreciate if someone could look at this issue at some point and provide feedback.
