Although my site's certificate is fine, ("openssl verify mysite.com.cer" resulted in OK), and my site is ssl-certified including green lock in the url-bar, my site is generating a fatal alert: bad_certificate whenever a subscriber in my WSO2 app executes an api.

I browsed through several stackoverflow-questions about 'bad_certificate' but found no solution.
To import my certificate I followed WSO2's docs:
openssl pkcs12 -export -in SSL_certificate_www_mysite_com.crt -inkey www.mysite.com.key -name "mykeys" -certfile mysite.com.cer -out mykeys.pfx
keytool -importkeystore -srckeystore mykeys.pfx -srcstoretype pkcs12 -destkeystore mykeys.jks -deststoretype JKS
keytool -export -alias "mykeys" -keystore mykeys.jks -file mykeys.pem
copied mykeys.pem and mykeys.jks to /usr/local/opt/wso2am-2.2.0/repository/resources/security/
keytool -import -alias "mykeys" -file mykeys.pem -keystore client-truststore.jks -storepass wso2carbon and answered yes to include the certificate
Then I had to change several configuration files to use mykeys instead of wso2carbon. So I did.
Then I restarted wso2-carbon, logged in and checked that mykeys.JKS showed up in the list of keystores, it does.
My site is correctly ssl-certified, green lock showing in the url-bar. All works fine, upto the point that logged in as Subscriber I try to Execute an API, which results in the response "ERROR - SourceHandler I/O error: Received fatal alert: bad_certificate" and the above-mentioned log coming from sourcehandler
This error is logged in repository/logs/wso2-apigw-errors.log and wso2carbon.log, but only this message, nothing else.
Where to look next to find why my certificate is not getting validated correctly?
