Error: Connection refused while token generating via WSO2 Devportal

问题

I am configuring WSO2 fully distributed APIM 3.1.0 with IS as KM and Dev/Publisher in one node. My IPs are as below,

Gateway IP - 172.42.42.20 DNS: gw.local.com
ISKM IP - 172.42.42.40 DNS: iskm.local.com
Dev/Publisher - 172.42.42.80 DNS: apim.local.com

All the configurations are done following WSO2 documentation and ansible scripts. But an error occurred while generating tokens via devportal. Using the curl command the tokens can be generated successfully. How to fix this issue? The carbon log is below. I saw many fixes for this issue, but none worked.

回答1:

Based on the stack trace, it looks like the Devportal is unable to connect to the key manager (IS as KM). Check the following config in the deployment.toml of the dev portal and it should point to IS as KM.

[apim.key_manager]
service_url = "https://[IS-AS-KM-host]/services/"
username = "$ref{super_admin.username}"
password = "$ref{super_admin.password}"

回答2:

If you are using hostnames, add them to the /etc/hosts file and change the IPs into hostnames configured in the deployment.toml
