Use the commands below to provide key information from your environment:
You do NOT have to include this information if this is a FEATURE REQUEST

What version of frp are you using (./frpc -v or ./frps -v)?
frp_0.21.0_linux_amd64

What operating system and processor architecture are you using (go env)?
server: centos7
client: centos7
Configures you used:

# cat frps.ini 
[common]
bind_port = 4396
bind_addr=0.0.0.0
auto_token=frp

# cat frpc.ini 
[common]
server_addr = x.x.x.x
server_port = 4396
auto_token=frp

[ssh_87]
type = tcp
local_ip = 127.0.0.1
local_port = 22
remote_port = 10085

Steps to reproduce the issue:

  1. ./frps -c ./frps.ini
  2. ./frpc -c ./frpc.ini

Describe the results you received:
