OIDC proxy error on port 9000 or 4200, when using infinispan caching, yet it works when not proxying on port 8080

[naris]

Overview of the issue

When using an external OIDC provider (keycloak) running a newly generated jhipster app, after setting the issuer-uri to the keycloak server, the application works if you go directly to the app on port 8080 but if you use the proxy on port 9000, or 4200, it errors out with "Error occurred while trying to proxy: localhost:9000/oauth2/authorization/oidc"

I have this issue with my existing project, which is where I encountered it after upgrading to jhipster 8.x, but it also happens with a newly generated project. This worked before when using jhipster 7.x

Motivation for or Use Case

To be able to use the BrowserStack proxy/HMR. I am able to work around the issue by going directly to port 8080 and not running npm start, but that is not how one is supposed to develop a jhipster app :(

Reproduce the error

1. Generate a jhipster application using oauth2/openapi authentication, you can either use the .yo-rc.json in this issue or generate a new application by answering the jhipster questions, specifying oauth2/oidc authentication.
2. set up or use an existing non-local keycloak provider on a different machine
3. set security:oauth2:client:provider:oidc:issuer-uri: https://<external_server>/realms/<realm_to_use> in application.yml
4. comment out or remove offline_access from security:oauth2:client:provider:registration:oidc:scope in application.yml
5. start the application itself with ./mvnw
6. go to the application's port (localhost:8080) and click sign-in, this will work
7. start the BrowserStack proxy by running npm start (which also automagically goes to localhost:9000 in your browser)
8. go to the proxied port (localhost:9000), if not already there, and click sign-in, this will not work and show "Error occurred while trying to proxy: localhost:9000/oauth2/authorization/oidc"
