It seems your coordinator is configured to reject coins bigger than 43000.00 BT while Kruw's coordinator max input is 1343.75 BTC, 5 bits less than yours. That means that coinjoing with your coordinator requires more cpu, memory and bandwidth.

Kruw's coordinator doesn't accept inputs under 0.00009999 BTC what prevents the creation of outputs below that threshold.

You can see these values in https://wabisator.com/

My suggestion is to lower the upper limit by a lot, 35 or 36 bits should be more than enough. Also, the lower limit could be adjusted a little bit.
