Problems importing bills from Wave

Hello, I have to import the bills from Wave to Akaunting. I downloaded the example sheet for bills and tried to copy-paste all the info in the right columns, but when I upload the xlsx file an error message shows up "Expected response code 220 but got an empty response". What should I do? Thanks in advance.

Hello Bernaus,

We could not reproduce any issues regarding your case. However, could you please try to first log out from Wave then login in again?
