Hi
I try to install kapacitor , after follow [instruction](https://docs.influxdata.com/kapacitor/v1.5/introduction/getting-started/) try to run below commands, but error appear:
```
kapacitor -config -skipVerify
flag provided but not defined: -config
Usage of main:
-skipVerify
Disable SSL verification (note, this is insecure). Defaults to the KAPACITOR_UNSAFE_SSL environment variable or false if not set.
-url string
The URL http(s)://host:port of the kapacitord server. Defaults to the KAPACITOR_URL environment variable or http://localhost:9092 if not set.
```
also try this one:
```
/usr/bin/kapacitord -config /etc/kapacitor/kapacitor.conf
lvl=error msg="failed to connect to InfluxDB, retrying..." service=influxdb cluster=default err="Get http://localhost:8086/ping: net/http: HTTP/1.x transport connection broken: malformed HTTP response \"\\x15\\x03\\x01\\x00\\x02\\x02\""
```
FYI:
config file same as [this](https://github.com/influxdata/kapacitor/blob/master/etc/kapacitor/kapacitor.conf)
Any idea?
Thanks,

Hi ,
I assume Influxdb is up and running ? 🙂
If you can get Kapacitor started you might get no data because the subscription-mode =“cluster” in your config file … as described here :
[https://docs.influxdata.com/kapacitor/v1.5/administration/subscription-management/](https://docs.influxdata.com/kapacitor/v1.5/administration/subscription-management/)
The `cluster` subscription-mode is planned for future versions of Kapacitor and [Kapacitor Enterprise](https://docs.influxdata.com/enterprise_kapacitor/). If used currently, subscription data will not be received
best regards

Yes influxdb, telegraf and cholonograf already installed and running.
I don’t use cluster mode and all subscriptions are disabled.
Any other idea?

can you try : /usr/bin/kapacitord ( without any arguments )
do you have more info in /var/log/kapacitor/kapacitor.log ?

Can you show the output of
show subscriptions
These may help also :

Thanks ,
Can you also logon to Influxdb and execute the command :
show subscriptions

here it is:

getting close -)
Looks that you have secured the influx database …
I guess the mode destination should show https in the show subscriptions output …
You may have to change some configuration in the kapacitor.conf file …
for example : subscription-protocol = “https”
Please check out following document …
[https://docs.influxdata.com/kapacitor/v1.5/administration/security/](https://docs.influxdata.com/kapacitor/v1.5/administration/security/)

Are you using a self signed certificate? the malformed http response looks similar to one i’ve had in the past regarding self signed certificates. If so, you need to tell Kapacitor to skip verifying the SSL certificate and also update the URL. As in, change it from _ **http** _://hostname:8086 to _ **https** _
```
[[influxdb]]
# Connect to an InfluxDB cluster
# Kapacitor can subscribe, query and write to this cluster.
# Using InfluxDB is not required and can be disabled.
enabled = true
default = true
name = "localhost"
urls = ["https://localhost:8086"]
username = ""
password = ""
timeout = 0
# Absolute path to pem encoded CA file.
# A CA can be provided without a key/cert pair
# ssl-ca = "/etc/kapacitor/ca.pem"
# Absolutes paths to pem encoded key and cert files.
# ssl-cert = "/etc/kapacitor/cert.pem"
# ssl-key = "/etc/kapacitor/key.pem"
# Do not verify the TLS/SSL certificate.
# This is insecure.
insecure-skip-verify = true
```
Changing the HTTP sections in Kapacitor config (near the top) won’t help. I’ve been there and tried.

I know that it is very late to answer 🙂 But for others like me - try to disable system proxy (check by env command).

Hi @IvanTheFirst … It is still pretty confusing for me as I am only the beginner. I will truly appreciate it if you could provide a detailed insight on it.
