Sunspec - SMA Tripower SE 6.0

Modbus works perfectly through YAML
SMA integration works perfect

HassOS as Unraid VM
reverse proxy through NPM docker
adguard home running as docker

Sunspec integration keeps giving connection issue during setup
slade ID (126) = SMA id (3) + 123

Is this port being blocked in any way or form? strange that modbus yaml is working perfectly,
