【TiDB Usage Environment】Testing
【TiDB Version】
【Reproduction Path】TIPD connection exception across different subnets
【Encountered Problem: Phenomenon and Impact】
I wrote a GUI using TIKVClient to connect to TiKV and read data, but there is still one issue that I haven’t figured out.

Connection test: When connecting within the same subnet, there is no problem. However, when connecting across different subnets, it fails to connect and does not report an error, only timing out after a certain period. I hope the developers can explain this to me.

Here are the code repositories:

Of course, I hope this tool can help everyone :laughing:

Not bad, thanks for sharing~

Network issues need to be logged and troubleshooted, which are largely related to the environment…

Whether it can be pinged or not

Try pinging it.

All ports are reachable via ping. I had the operations team check, and there is no data coming through on the TiKV 20160 port.

I haven’t done operations and maintenance, and I’m not very familiar with networking, so I’m relatively weak in this area.

So is it a firewall issue? Have you tried using telnet?

tracert -d ip x.x.x.x Check for yourself where it is not connected.

| username: 表渣渣渣 | Original post link

I have tried it, and it works.

| username: 表渣渣渣 | Original post link

I’ll give this a try.

This clearly indicates that the intermediate node network is not connected. Just ask the network administrator to adjust the policy.
