This specific type of Generic Communication error: “Couldn’t resolve host name” is usually related with the fact that URL-license-field is not empty when you 1. launch Byos, 2. click on Help/Register, 3. select "I have a Shared-Seat license" and 4. click on "Next".
Due to this, Byos does not know if the user wants to use this shared-license instead of the MW or individual one.
If after deleting the content of that field and restarting Byos, you still experience this same error, please contact support@proteinmetrics.com
