V3.60-25 MPPT connectivity issues

Venus OS v3.60~25
I have lost communication to the MPPT450/100 and it keeps on saying BMS connection lost,
sometimes it comes on works for a few minutes , then disappear again for like two days

Hi, I don’t believe anything in the release affects this, could you please roll back to the previous backup release on the GX and see if it disappears. Thanks.
