EPC 1502 - can't write data to InfluxDB using C#

Hello,
I have InfluxDB running on a PxC EPC 1502 and I try to send data via .net Client library using InfluxDbClient. On my local influxDB i have no problem but once i change the URL to https://192.168.1.100:8086 with the new token the data gets lost somewhere. Moreover I get no error while writing.. Do i need change some settings in the EPC WBM?

And a second thing: where can I find the influxdb.conf file? I want to disable the verfying process regarding the server protocol because it says its outdated
