no function of modbus1 in iobroker after update

[LCNJoe]

After the update to 6.1.0, no data is available from the modbus1 instance. Poll error account .. Restart adapter system.adapter.modbus.1 because enabled.

Modbus0 to SMA inverter continues to work well. Modbus1 queries a smartmeter SDM630 via a PE11 converter (TCP-modbus). The wallbox continues to query the smart meter and data is processed.

What has changed in the new version? What can I adjust?

Thanks for your help

[LCNJoe]

Hm ... in fact the adapter can not connect/get no data from device and so restarts itself after some tries to retryx cleanly

[LCNJoe]

It worked for a year with the previous version. Therefore, something in the adapter must have been changed in the current version. A new variable or library perhaps?

[Apollon77]

Did you tried reinstalling the old version to verify it is aboit the version and not about the device?

[LCNJoe]

I can do it, how can I install the old version? And which device do you mean? The TCP modbus device works perfectly, it is queried correctly by my wallbox.

Admin - expert mode - adapters - there is an icon right where you get a list of previous versions and can choose one to install

[LCNJoe]

OK, I already found it, thanks.
the previous version is running. I've attached the log, maybe it will help with troubleshooting.
