i can't sinc anymore with the last version, anyone have the some problem?
No, i can sync whether on mainnet, testnet or signet. You might want to ask help on "Bitcoin Technical Support" board while providing some information (e.g. debug log, how do you connect to internet).
i didn't change anything about internet connection or firewall therefore it's not that, there was a warning about consensus when i switched from 23 to 24 version, then the warning disappeared and now it's not synching anymore
