this is result

this is result

as seen on tronscan, it returned "Failed -Out of Energy>"
you can try increasing kwargs["fee_limit"] = 5000000 to kwargs["fee_limit"] = 20000000 (20 TRX) and try again

Thank you for your guidance
Yes, the transfer was done by increasing the fee limit.
that was perfect
<3 <3 <3 ;)

This is not working on my side. I do not have multi-signature authority. See result below.

RESULT {'code': 'SIGERROR', 'txid': '3455e6e8e17b2ac99725bf461cde9b505a5f5d516770f5f551700d3e2f7441d9', 'message': 'Validate signature error: 09a1c7cdf01973d5704f9469606a814a83107583c96b6ada4e7dc17c280f417e22d5d68fe7c607c682b8d12712a1d8adf2875cd9061e4de4d95094bdb65c2d641c is signed by TKx1TtevcLSMst73ZRZLKfVc7wEfpVwuBn but it is not contained of permission.'}

I am also want to send from a multi signature wallet which i have the same problem!
