SR2, can't access Deepl, can't reinstall it

Hello
after installing Trados 2021 SR2,
1 Deepl was no longer accessible.
2 when trying to access the AppStore from Trados: inaccessible. "Check your internet connection". Yet I can access RWS from the browser all right.
There, the installation exe fails




It is accessible from my (fortunately kept) Trados 2019.
This is impacting various projects; I have a large job due in a week.


Thanks for help
