In my etcd ssl configuration sni has "*.yestae.com" configuration ，

[root@test-open-api apisix-dashboard]# etcdctl_new  --endpoints=http://127.0.0.1:3379  get /apisix/ssl  --prefix

Interesting. Can't reproduce in my side. I set the SSL configuration via apisix's admin API:

# etcdctl get /apisix/ssl  --prefix
/apisix/ssl/
init_dir
/apisix/ssl/1
{"cert":"...","id":"1","status":1,"key":"...","snis":["*.yestae.com","autodiscover.yestae.com","mail.yestae.com","owa.yestae.com","www.yestae.com","yestae.com"]}

But I got: radixtree_sni.lua:208: match_and_set(): sni: test-api.yestae.com.

Maybe you need to add more log in radixtree_sni.lua.

Look strange to me. Could you provide a minimal example to reproduce the issue? Will change SSL configure make this problem disappear?

Thank you very much, I have found the cause of the problem: Because my apisix-dashboard uses 2.0-rc2, my ssl configuration is configured from the dashboard, there may be incompatible configuration formats, I solved it through apisix-admin api Fix the problem, thanks again for your help
