Describe the bug
Hello team, I am trying to push logs from fluent bit to kafka along with some kafka authentication information but I get error "fluent-bit#producer-1: [thrd:sasl_plaintext://172.26.24.84:31504 /bootstrap]: 3/3 brokers are down"

Are they down?
Is that the right config for them?
Are those IPs and ports routable from wherever you are running FB? Debug images can be used to test this easily.
Is it in cluster, external?
Clarify the version - latest might not be pulled often so is it 3.1.8?
Can you fill out the rest of the environment information?
