ISSUE –> When we are invoking external webservices some times we use to get the below errors.
Webservice invocation failed , unable to access the end point url.
## First we need to check if the host is accessible from your server or not .
For this you need to ping the external host from your server .
Ex:- ping hostname.com
- If you have not received any response then your external host is not accessible.
In these cases you have to check with external system if their server is up or not.
Some times may be your server firewall is blocking the call , in those cases you have to open the firewall on particular host.
2. If you have received unknown host error , then you need to check if the host entry exist in the server host file or not .
Location :- /etc/hosts
## Second we need to check if the external webservice has security assigned to it.
In those cases you have to check if you are passing the correct credentials to access the service.
If the service is using any wss security types then you need to go and check if the token configured in your EM is working or not .
