SBF no longer uploading

I have had SBFspot uploading to PVOutput without issue for quite some time running in a Ubuntu VM on a NUC.
On 24/08 I had a power failure during the night and the NUC shutdown. Since coming back online, data has not been uploading to PVOutput.

Looking at the database, there is current data in vwSpotData, however the latest data in vwPvoData, etc is the last reading from the inverter before the power failure.

I am running I believe V3.3.1 of SBFspot using SQLite.

Hoping someone may be able to assist with getting the uploads going again.
I have tried running /usr/local/bin/sbfspot.3/SBFspotUploadDaemon manually to make sure the daemon is running, but still nothing is being uploaded. So, I believe it is probably an issue with the database?

Cheers.
