8.19.1 throwing REST errors since 1.45am

[pacemaker82]

Describe the bug

Something related to
"Inverter 0 unable to read charge window time as neither REST, charge_start_time or charge_start_hour are set"

This started at 1.45am, and has continued since. I obviously took no action at this time as was asleep.

Looks to be related to GIVTCP at 1.45am, after Predbat set the charge schedule... any reason this would randomly happen?

I am restarting GivTCP to see if that helps (v3.1.6)

Restarting GivTCP has not resolved the issue

I've not been able to resolve the issue with GivTCP 3.1.6, even after hard reboot of HA device. Therefore rolled back to GivTCP 2.4.9 add on, restarted Predbat and I have a plan again. Will stay on 2.4.9 I think ...

Documenting here in case others have same problem (certainly seems others have this, no one has offered a solution that I can find...)

I have been experiencing similar.
I first had issues with givTCP 3.1.6 but I have been keeping abreast of prepay updates to 8.19.4.
Predbat has been crashing and/or freezing.
I have now gone back to v8.19.1.

I may downgrade givTCP back to 2.4.9 but I have only just got it back after restoring from a backup.
