Basicstation tls work just without CA path

i’m sucess to work with basic station that communicate with gateway bridge in secure mode TLS, but when i specify the CA path on gateway-bridge.toml, the basic station can’t connect to the gateway bridge, i see this solution in this topic :
brocaar solution
Why the gateway bridge can’t use the CA to permit to basic station to check this ??
When generating all certificat for gateway bridge and basic station with “chirpstack-certificates” , i use the default configuration, because i can’t find in the gateway-bridge.toml, where define the “CN” ! by default in “chirpstack-certificates” the CN is “lora-gateway-bridge”

I’m closing this topic. There is no need to post the same question twice (you already posted your question in Using secure websockets with Basic Station).
