Numerous Auto-restart triggered when GivTCP has Error getting data from cache

[apone2000]

Describe the bug
Several times per day Predbat is having to restart givtcp as it think its timed out. Not sure if it has or if predbat is detecting failure incorrectly, so putting bug here and on givtcp issues list. On calling restart all comes back to life, so the restart scripts all work fine.
britkat1980/giv_tcp#388

Predbat version
1.2.4 / v8.18.12

Environment details
GivEnergy AC3 inverter with 3x5kwh batteries.
D0.210-A0.210 inverter firmwar
3020 battery firmware
RTC enabled

HAOS 15.1 running in virtual box on a PC, Home Assistant Core 2025.4.1

Note: this may be a predbat issue or givTCP, but started when i did the givtcp upgrade.
britkat1980/giv_tcp#388 bug raised on givtcp board too

Since upgrading to giveTCP 3.1.6 for RTC entities I now get several restarts via Predbat each day.

Have you made any progress on this? Restarting GivTCP has not resolved it for me, so now Predbat is dead.
