Hi there, mgThu.
I tried to connect to Transferwise and had no issue.
We'll encounter this error if the connection with our server was interrupted or corrupted. I have some steps you can perform so we can fix this.
Let's first start by using an incognito window and connect it from there. You can also clear your browser's cache so the system can start fresh. Additionally, make sure that the browser is updated.
Let me share the reference on how to connect the bank account.
Post again here if you have more questions. Have a great day!
