Accounts.csv not being loaded

I have a someone weird issue with Accounts.csv
I have two machines, both running 1.59.6
On one of them, I edited the AccountsExample.csv and renamed to Accounts.csv. This worked just as expected.

I now simply copied the content of this file to my other machine and created an Accounts.csv there as well. However it is not being picked up by Zorro on that machine, the dropdown only shows Real/Demo account, as if there was no Accounts-file. What could possibly cause this?

Maybe file permissions?

Actually it turned out that I had forgotten to add my Zorro S key...
