I'm following WSO2 Admin Services instructions for 4.5.0 version of WSO2APIM. I can fetch WSDLs for different services and generate requests in SOAP UI, hovewer I can not login my admin user in AuthenticationAdmin service and as a result can not use other services without session id. Below request that I use in SOAP UI. Do I need to have some additional headers in a request (currently no headers)?
URL:
https://api-temy.dev.com/services/AuthenticationAdmin.AuthenticationAdminHttpsSoap11Endpoint
My WSO2 server is running on OracleLinux VM, and I have a proxy that maps https://api-temy.dev.com/services to https://api-temy.dev.com:9443/services
Request:

In Carbon logs I see following errors:

It seems you are trying to access the Admin service through the wrong port. Try accessing through the port `9443`.
https://your-host:9443/services/AuthenticationAdmin.AuthenticationAdminHttpsSoap11Endpoint
Your DNS `api-temy.dev.com` is probably mapped to expose the GW ports 8243/8280, so you may have to add an additional entry to expose services through port 9443 as well.
As a side note consider using API Manager Rest APIs instead of Admin services.
