LDAP user can't connect after upgrading to grafana oss 9.1.7

After upgrading grafana to 9.1.7 on a server running Ubuntu 20.04.4 LTS, LDAP user can’t connect.
The error is :
“logger=context traceID=00000000000000000000000000000000 userId=0 orgId=0 uname= t=2022-10-07T11:56:25.286216542+02:00 level=error msg=“Error while trying to authenticate user” error=“tls: server selected unsupported protocol version 301” remote_addr=x.x.x.x traceID=00000000000000000000000000000000”
After downgrade to 9.1.6, everything is OK.
