hi @Grzegorz welcome ! , can you try a telnet from the server where telegraf is running to the database server ? ``` telnet serverhostname influxdbport ``` or ping the influxdatabase with ``` curl -sl -I http://yourdatabasehost:8086/ping ``` can you check on the database server if influxdb is listening with ``` netstat -ntlp |grep -i influxd ``` ---

I am working on Windows servers. Normal ping like " ping mydatabasehost" is working. Telnet “Could not open connection to the host, on port 8086: Connect failed” ---

The telnet to port 8086 failed which means the port is probably not open ? Does a telnet to port 8086 work on the other server ? ---

Hello, first try to `curl -v http://YOURINFLUXHOST:8086/ping` If this is not working, your influxdb is not reachable (off, network problems etc) If this is working, maybe your telegraf has problems with reconnects: [https://github.com/influxdata/telegraf/issues/5905](https://github.com/influxdata/telegraf/issues/5905) Greetings. ---

If 445 is really the right port, influxdb is not available here. Are you sure this is the right port? So you either influxdb is not running or you have a network problem. Try to debug from your host on 10.16.66.177 with ``` curl -v http://127.0.0.1:445/ping ``` and stuff like that ---
