Library functions make requests via ton.tl.functions. Each of the classes is a reference to the libtonlibjson method (full list).
To enable debugging of library actions, need to do this:
import logging
logging.getLogger('ton').disabled = False
logging.getLogger('ton').setLevel(logging.DEBUG)But apart from visible errors, the action can simply last indefinitely in time. This means that the error occurred inside libtonlibjson OR the selected liteserver is not responding. In that case, we need to see what's going on inside:
await client.set_verbosity_level(5)If it seems that the problem is in the lite server, you need to change it, reinitialize the library with a different ls_index:
client = TonlibClient(ls_index=N)
await client.init_tonlib()
