How to post data using HTTP cURL from a server which is behind firewall?

1

We are using HTTP cURL command to post data into influxdb from a server which is behind firewall but
getting below mentioned error:-
“curl: (7) couldn’t connect to host"

Our all servers are behind the FIREWALL and we can not remove the same.

Wanted to know if there is any other alternative to post data using HTTP API cURL ?

This sounds like service port “8086” (default) access issue. How do you usually access services on servers behind Firewall; the same should be applicable to this port. Unless the Firewall is configured to specifically block the POST requests; in that scenarios enabling the HTTPS access should help.
