If you have access to more than one Visma eAccounting company, you should get a list in https://cloudmanager.connectmyapps.com/ and be asked to choose which one to connect to.
If you don't get the list after clicking Authenticate, it might be because you have set a "default" company in Visma Accounting.
To avoid this, please remove the default company by logging into Visma eAcccounting. In the top right menu, select default company and remove any stars from the list.
