Check that you have the required scopes (read for Event Streams) and if so try to change the base url you're using for both the API and token request.

The base URLs available are:

 48 
 49     US1 = "api.crowdstrike.com"
 50     US2 = "api.us-2.crowdstrike.com"
 51     EU1 = "api.eu-1.crowdstrike.com"
 52     USGOV1 = "api.laggar.gcw.crowdstrike.com"
 53     AUTO = "api.crowdstrike.com"                

If you are using the default URL (AUTO) try changing the values set in /opt/crowdstrike/etc/cs.falconhoseclient.cfg in order to use the US2 or the EU1

api_url = https://api.crowdstrike.com/sensors/entities/datafeed/v2
request_token_url = https://api.crowdstrike.com/oauth2/token

---

US-2

api_url = https://api.us-2.crowdstrike.com/sensors/entities/datafeed/v2
request_token_url = https://api.us-2.crowdstrike.com/oauth2/token

---

EU-1

api_url = https://api.eu-1.crowdstrike.com/sensors/entities/datafeed/v2
request_token_url = https://api.eu-1.crowdstrike.com/oauth2/token
