I've been running nightscout-librelink-up sucessfully for about a week now. Tonight at 7:28pm CEST it suddenly stopped working and now reports the following:

[info]: renew token
[error]: "very long string of digits and characters"
[error]: Invalid authentication token. Please check your LibreLink Up credentials Cannot read property 'status' of undefined
[error]: LibreLink Up - No AuthTicket received. Please check your credentials.

The error seems to be caused at line 163 in index.ts:
if (response.data.status !== 0)

Any idea what could be causing this? I checked the credentials in the librelink up app - they continue to work there.
