Reverse proxy and server redirect - redirect

I have Angular app in IIS, which is configured to work as reverse proxy, directing requests to node backend running in same server. From node there is a redirect third party login. The problem is that when trying to redirect to this third party login page from my node backend, something adds to URL my apps URL like:
myapp.com/thirdpartyurl
even though it should only be:
thirdpartyurl
Does anyone have a clue what might be wrong?

Running User Interfaces and APIs behind keycloak gatekeeper

New to keycloak, and authentication in general, so sorry for missing something obvious, and not using accurate terminology.
I'm trying to run a simple Angular UI that talks to a Java (dropwizard) API. I'd like both of those to need auth. I'm (almost) able to get them running fine behind keycloak and keycloak gatekeeper using a single realm and a confidential client. In this case gatekeeper has an upstream-url that is a traefik instance, that then routes to either the UI or API docker container. Something like:
Gatekeeper upstream-url ----> Traefik (my.domain/*) ----> UI (my.domain/ui/*)
\---> API (my.domain/api/*)
This works fine until the session times out, and when the user on the (already loaded) UI page clicks a button that tries to send an ajax request to hit the API (eg https://my.domain/api/getstuff), then Gatekeeper redirects (ie 301) that to the the keycloak login page. This redirect is a little nonsensical for an API request...
At this point both my UI and API projects are auth agnostic (ie they are not running any of the adapters etc just yet - I'm relying on the docker setup to prevent "direct" access to UI and API for now. I'll add the adapters once I need to know something about the user). I can see in https://www.keycloak.org/docs/latest/securing_apps/index.html#configuration-options the autodetect-bearer-only option which seems to describe my issue, ie
It allows you to redirect unauthenticated users of the web application to the Keycloak login page, but send an HTTP 401 status code to unauthenticated SOAP or REST clients instead as they would not understand a redirect to the login page
but seems to apply at the adapter layer, ie after gatekeeper in my scenario.
this seems similar too.
I think I want unauthenticated (eg never logged in, or timed out) access requests to https://my.domain/ui/* to be redirected to the keycloak login page, but https://my.domain/api/* to 401.
And from https://my.domain/ui/somepage the ajax request to https://my.domain/api/getstuff to use the JWT/token/cookie that the browser has from the login (which is working now).
How do I do this? What stupidly obvious step have I missed!?
Unfortunately, you cannot tell Gatekeeper to return 401(403) response codes instead of redirect. There is similar issue: https://issues.jboss.org/browse/KEYCLOAK-11082
What you can do is to remove Gatekeeper completely and implement public client authentication on frontend (JS adapter) and bearer-only client on backend (Java Adapter). If your Java application serves frontend you can implement only confidential client authentication and return 401(403) response for /api/* requests.

REST API with Single Page Application over HTTPS on Firefox only

I am developing a web service using REST API. This REST API is running on port 6443 for HTTPS. Client is going to be a Single page application running on port 443 for HTTPS on same machine. The problem I am facing is:
While I hit the url say: https://mymachine.com/new_ui I get certificate exception for an invalid certificate because I use a self signed one, so mymachine.com:443 gets added to server exception. But still requests doen't go to REST API as they are running on https://mymachine.com:6443/restservice. If I manually add mymachine.com:6443 to server exception on firefox it works but it will not be the case in production for customers.
Some options that I thought are:
1. Give another pop up and ask to add REST server on port 6443 exception too.But this doesn't look proper as why an end user should accept the cerf for same domain twice. Also REST api server port can change.
Can we programmatically add exception for domain and both the ports in one shot? Ofcourse with the consent of the user. 3. Use a reverse proxy. But then its going to have memory footprint on our system. Also it will be time consuming.
Please suggest some options. How do I deal with it. Thank you

Circumventing web security limitations between two sites on the same server

I'm using Eclipse to develop an app that consists of an Angular 2 front end and a Java REST back end.
For the front end, I'm using the Angular CLI plugin, which starts the app by issuing an ng serve command to the CLI. This command sets up an http server on port 4200.
For the back end, I'm using an in-company framework that launches in Jetty within Eclipse in port 8088.
While both these ports are configurable, by nature of the frameworks and plugins in use, they'll always be distinct.
Authentication works via an OAuth2 service that is also deployed to port 8088, as part of the framework. This service sets a cookie which certifies the browser session as authenticated. I have verified that this service works correctly by testing it against a Swagger instance of the REST API (also running in 8088 as part of the same framework).
The problem is that when the browser is aimed at the Angular 2 app on :4200, its internal REST API requests to :8088 aren't carrying the authentication cookie. Presumably, this is because of cross-site protection.
Is there any way for the app or the framework to tell the browser that these two "sites" are actually part of the same system?
Alternatively, if I have to configure the dev browser (Chrome) to work, I can live with that too. However, I've tried the --disable-web-security --user-data-dir recommendation, but the cookie still doesn't show up on the requests.
Lastly, I have Apache installed on the dev machine. If I can set up appropriate vhosts and use it as a proxy so that the browser thinks it's all the same, that would probably work too. It would just be a matter of intercepting all /swagger and /api requests and sending them to :8088, and all forwarding all other requests to :4200. However, I've been banging my head against mod_rewrite and mod_proxy and haven't been able to come up with anything that works.
I think what you're looking for is
withCredentials = true

OAuth access_denied on login from all providers after server IP change

We recently changed the IP-address on a server hosting one of our services based on .NET Web API 2.
The service is using OAuth2, providing external logins via Facebook/Google.
We're still using the same server and the same host name for our services, only the IP-address has changed. Now I'm getting back my login URL with "&error=access_denied" whenever I try to login using Facebook/Google.
I have checked every setting in both Facebook's and Google's developer consoles but nothing seems to apply. If I remove the OAuth redirect URI, I get an error that the URL is blocked, so the settings seems to take effect.
What have I missed?
Funny how asking a question makes you think even more outside of the box. The culprit was that wrong DNS-server was set on the web host.
I'll see myself out...

http tp https forward some requests in haproxy

Currently all traffic is coming to backend servers, which is running on port 80. However we want to redirect some pages to https. This means that whenever the customer hits on login page, logout page present in the website. It should be redirected to https.
When a customer hits on the login button it redirect to https but using haproxy it doesn't work.
https://XXXXXXXX.com/customer/account/login/
We have already installed ssl in both the servers.
However, redirection is not working from http to https.
Please suggest what I should try.
It would be best to use HAproxy to terminate the SSL and talk to the backend servers via HTTP rather than having both HAproxy and the webserver doing SSL.
There is a good SSL setup tutorial here https://www.digitalocean.com/community/tutorials/how-to-implement-ssl-termination-with-haproxy-on-ubuntu-14-04
