I upgraded to the version that was knocking on the door:
Logitech Media Server Versjon: 7.7.6 - 1521467459 @ Thu Mar 29 16:46:01 WEDT 2018

But I still got only the LMS itself as "Music source".

I was logged in to https://mysqueezebox.com

In LMS I opened "My services" and clicked on "Service list" and was
redirected to https://www.mysqueezebox.com/ where I wasn't logged in.

Could it be an issue with https://mysqueezebox.com vs
https://www.mysqueezebox.com?

I logged into https://www.mysqueezebox.com/ and then reopened "My
services" again and this time it redirected to a logged in
https://www.mysqueezebox.com/

But "Music sources" still only listed the LMS itself.

I opened the LMS settings, selected the mysqueezebox tab, and tried
setting the password, only to be told that "Invalid username or password
for mysqueezeboks.com".

Inserting the old password works without error messages from LMS, but
the old password can no longer be used on mysqueezeboks.com itself.

What's complaining in LMS when I put in the new password?

Why does it work (or at least: not fail) with the old password?

Thanks!
