Current behavior

Hi @Sebastian I am trying to run the squidex locally
taking support of this document
According to above Document
i) First of all i installed docker using below which is also present in the document
ii) Started Backend using .net 7 at port 5001
I start the backend using "dotnet run --environment “Development” command
iii) Then start frontend at port 3000
using command ng s
After starting starting frontend “Login to Squidex” screen appears but Login popup doesn’t appear

But After starting backend at port 5001 it gives error

The error which i get in the terminal is

Have you installed these certs?

Hi @Sebastian Thank you very much for the very swift reply
Yes all the certs are installed in the project
But the main doubt for me is how to install that certs in the system

Hi @Sebastian Using Doc project
In that also i had to add the reverse proxy using nginx in docker

Are you using windows? Just use the install.bat file and it should work.

I do not understand if you want to run it for development or just run it locally.

Thank you very much @Sebastian for the reply
No i am using Ubuntu 20.04 and i want to run locally
I will write our current scenario where we are stuck
Our frontend runs on port 3000
Below screenshot show Login to Squidex but when we click on button it gives us 400 error

Now certificate issues for https is solved using nginx

The main error we get is backend and our backend works at 5001 port

At this error we are totally stuck

Please format the code properly next time.

I am not a linux user but this is how it works:

  1. The frontend is hosted under :3000
  2. The backend acts as a reverse proxy and calls the frontend. Therefore you have to open :5001 in the browser.
  3. To support all authentication scenarios the backend must run under https.
  4. To prevent mixed content issues the frontend also must run under https.

Therefore you have to install the certs, otherwise the backend cannot run the frontend. But I am not sure how to do it under ubuntu.
