We used the following tutorial to set up an Oracle APEX Application with an Azure based social sign in: https://oracle-base.com/articles/misc/azure-ad-authentication-for-oracle-apex-applications
It works somehow, but the redirect url provided by apex seems to result in the user getting redirected to https://our-domain/:80/ords/apex_authentication.callback?... The browser then displays an error message. If the user removes ":80" from the url, and does not change anything else, he will get redirected to the APEX application and everything works.
Our machine, hosted by Azure has the following uname -a:
Linux servername 5.15.0-1020-azure #25~20.04.1-Ubuntu SMP Thu Sep 1 19:20:56 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
We are using docker for the deployment with the following two containers:
container-registry.oracle.com/database/enterprise:21.3.0.0
container-registry.oracle.com/database/ords:22.2.0
The APEX version is 22.1.
We have not changed anything to the base configurations of Tomcat, ORDS or APEX. SSL/TLS is handled by a nginx reverse proxy that redirects to our APEX application.
This is the chain of URLs from the browser debugging tools:
apex_authentication.get_callback_url has the :80 in it, but we found no way to change it:
We will provide all further information if it helps and are very thankful for all help!
