--sources (Access List) Stops Traffic？

[githubflyideas]

When I use --sources=172.19.3.0/24 to define allowed client IPs, I cannot access the Load Balancer (LB) service from my browser.

The service is accessible and works fine when the --sources parameter is removed. My client IP is correctly inside the 172.19.3.0/24 range.

I check packets: My client's IP address is seen by tcpdump

loxicmd create lb 10.252.233.181 --tcp=8080:80 --endpoints=172.19.1.32:80,10.252.34.25:20 --mode=onearm --sources=172.19.3.0/24

Result: My browser cannot open the service.

I run this command (It works):
loxicmd create lb 10.252.233.181 --tcp=8080:80 --endpoints=172.19.1.32:80,10.252.34.25:20 --mode=onearm
Result: My browser opens the service normally.
