External storage password error

I’m running Nextcloud Hub 9 (30.0.6) on a fresh installation of Ubuntu 24.04. I have a brand new 5tb hdd that is mounted at /media/rakelbara/Expansion.

I have installed the External Storage App, but when I try to add my drive, my password is not accepted. I can see this is a bug that others have experienced. But I haven’t figured out how to get around this issue.
Can someone help?

Thanks in advance!
