Hi, could you please provide your configuration file?

[SakaZhang]

i got same prob.

[fernvenue]

Could anyone provide configuration? I don't think we can reproduce this issue without any useful information.

[fernvenue]

You guys just keep saying that you all experiencing this, but no one provide any configuration example or useful information, what a joke.

This message is produced on my server when a port scan is received. If I scan the ports of my server with nmap, this message shows up.

sry about that. I turn to use frp and no more pay attention to this issue.
Here is some info:
os: 5.15.0-91-generic #101-Ubuntu SMP Tue Nov 14 13:30:08 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

version: rathole v0.4.8

client config:

[client]
remote_addr = "MY_DOMAIN:28888"

[client.services.outgoing]
token = "isGaDvTQBHYdXPr6"
local_addr = "192.168.50.252:80"

server config is lost, but it looked like the example, then ran and got error.

@SakaZhang You may need to reproduce this issue then provide the configuration file.

Don't be so rude. I am able to reproduce issue with the default configuration. Configuration file is the least important thing here.

The cause is simple and clear.

Just as the message itself indicated, someone else is sending invalid bytes into that port. It is an error that should be ignored.

In my case this error happens when I use cloudflare proxied domain

[server]
bind_addr = "0.0.0.0:2053"

[server.services.my_custom]
token = "use_a_secret_that_only_you_know"
bind_addr = "0.0.0.0:443"

[server.transport]
type = "tls"

[server.transport.tls]
pkcs12 = "file.pfx"
pkcs12_password = "passwd"

[client]
remote_addr = "my.domain.com:2053"

[client.transport]
type = "tls"

[client.transport.tls]
trusted_root = "/etc/ssl/certs/ca-certificates.crt"

[client.services.my_custom]
token = "use_a_secret_that_only_you_know"
local_addr = "127.0.0.1:443"

my.domain.com is behind cloudflare proxy
