Hi, I met this problem

Hi!

The pool deposit was added to tx_out calculation - which is 500 ADA. that is not needed in case of re-registration/modification of node params.

the problem in general:

Transaction errors: ValueNotConservedUTxO

Change pool margin without paying pool registration again - guide needed

or just follow the pool registration update section carefully - pool deposit not added when calculating txOut during re-registration: txOut=$((${total_balance}-${fee})) echo txOut: ${txOut} the initial registration contains the pool deposit: txOut=$((${total_balance}-${poolDeposit}-${fee})) echo txOut: ${txOut}
