Hi Team ,

Advance thanks for helping me out  
andI am trying to monitor the flask application metrices I am getting an error like given below  
Failed to submit message: "Unable to reach APM Server: HTTPSConnectionPool(host='IP', port=8300): Max retries exceeded with url: /intake/v2/events (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE\_VERIFY\_FAILED] certificate verify failed: unable to get local issuer certificate (\_ssl.c:1007)'))) (url: [https://IP:8300/intake/v2/events](https://IP:8300/intake/v2/events))"

The Flask code is

import requests  
app = Flask( **name** )  
app.config['ELASTIC\_APM'] = {  
'SERVICE\_NAME': 'amtfleet',  
'SECRET\_TOKEN': 'hi',  
'SERVER\_URL': '[https://IP:8300](https://IP:8300)',  
'ENVIRONMENT': 'my-environment',  
'LOG\_LEVEL': 'debug',  
'DEBUG': True  
}  
apm = ElasticAPM(app)

Let me know in the code what to add to get it verify the certificate for self-signed certificate I have a fleet-server.crt and key but I am not getting how to add it as trusted certificate.

Hi @Yogesh_AS,

You look to be right that it's a certificate issue. Have you tried specifying the [SERVER\_CERT option](https://www.elastic.co/guide/en/apm/agent/python/current/configuration.html#config-server-cert)? I see an example snippet in [this GitHub issue](https://github.com/elastic/apm-agent-python/issues/496) which could help.

Let us know if that resolves your issue.

Hi @carly.richmond ,

Thanks for helping me out I have added these parameter.  
its worked.

from elasticapm.contrib.flask import ElasticAPM

app = Flask( **name** )  
app.config['ELASTIC\_APM'] = {  
'SERVICE\_NAME': 'amtf',  
'SECRET\_TOKEN': 'aamt',  
'ELASTIC\_APM\_SERVER\_URL': '[https://10.10.100.59:8200](https://10.10.100.59:8200)',  
'ENVIRONMENT': 'my-environment',  
'INSTRUMENT' : True,  
'VERIFY\_SERVER\_CERT' : True,  
'SERVER\_CERT': '/root/fleet-server.crt',  
'SERVER\_CA\_CERT\_FILE' : '/root/ca.pem',  
'LOG\_LEVEL': 'debug',  
'DEBUG': True  
}  
apm = ElasticAPM(app)

I have a doubt that when we install elastic-agent is it possible to get APM & Infra Metrices without installing APM Agent in managed environment.
