Please upload for program file (.fcfx) if you want people to be able to help.

Need to use 'full editor & preview' then 'Attachments' (beneath message)

tell me what algorithm of the program I should use so that the connection is stable, if the connection is lost, so that it can be restored

I think the idea is to check if an error has occurred and re-connect if needed (looking at examples in the wiki at https://www.flowcode.co.uk/wiki/index.p ... IoT/Cloud))

So something like:
