I used the old configuration. (version 1.9.7). no problem.  
Old config, i look haproxy\_stats (LastChk in L4) is good.  
but,when update to 2.2.I found GRPC-config problems.  
Same configuration when I upgrade to 2.2,the configuration fails. http-grpc can not access.  
2.2 config. i look haproxy\_stats (LastChk in L7) is bad  
I do not know problem is?how fix it.

```
install haproxy 1.9.7
make TARGET=linux2628 USE_ZLIB=yes PREFIX=/usr/local/haproxy
make install PREFIX=/usr/local/haproxy
------------config------------------------
frontend grpc
    mode http
    option forwardfor
    option http-use-htx
    bind :80 proto h2

When I down grade to 2.1.8, it’s OK.So I think 2.2.2 GRPC has some problems
