Hi.
I try to use HA-Proxy version 2.1.3-1ppa1~bionic with Let's Encrypt and
ssl-check.
My Serverline looks like this
```
server static_stor storage.sbg.cloud.ovh.net:443 resolvers mydns check check-ssl
check-sni str("storage.sbg.cloud.ovh.net") ca-file
/etc/ssl/certs/ISRG_Root_X1.pem backup
```
The log entry for the check is this.
```
Mar 2 22:13:17 lb1 haproxy[17027]: Backup Server be_static/static_stor is DOWN, reason:
Socket error, info: "SSL handshake failure", check dura
tion: 7ms. 0 active and 0 backup servers left. 0 sessions active, 0 requeued, 0
remaining in queue.
```
I have tried also the fullchain.pem but nothing works.
I'm sure I miss something simple and hope that someone can help me to fix this.
Best regards
Aleks
