Miningcore Solo Mining pool based on rmt-miningcore forked from miningcore-xiaolin1679

I have setup miningcore solo mining pool on docker container that is working fine. Though facing following issue:

As per above image pending shares transferred to pending balance but these are not transferring to PAID balance with following error.

[2024-12-31 03:45:02.9038] [I] [khaaaicpu] [Bitcoin Payout Handler] Paying 110 CPU to 1 addresses
[2024-12-31 03:45:03.1267] [E] [khaaaicpu] [Bitcoin Payout Handler] sendmany returned error: Fee estimation failed. Fallbackfee is disabled. Wait a few blocks or enable -fallbackfee. code -6

Any advise how what to change in config.json file.

thanks

Just to update, i wish to communicate that it has been done by adding fallbackfee=0.00001 to coin.conf file.
