Hello,

I have followed your installation guide here (https://github.com/thm-projects/arsnova.click-v2/blob/master/documentation/Frontend-Installationguide.md) but I'm stuck on the last step. I get following output:

> [email protected] dev:ssr /net/vcac-ubuntu16/disc1/www/html/arsnova-clicks/arsnova-click-v2-frontend
> ng run frontend:serve-ssr

Is there anything I can do? I tried also the docker version but I cant access anything localhost:4200 neither 4210.

The text was updated successfully, but these errors were encountered:

Hello,

this issue is known, we had a quick fix implemented in the code, but currently the quick fix doesnt work.
There is a manual way to get by this problem, I will add this to the installation guide within the coming days so stay tuned!

PhilippSautner97 · 2020-12-12T09:06:40Z

The fix is now added to the installationguide, have fun!

SaifAlDilaimi · 2020-12-12T15:06:15Z

awesome! I will test it monday!

Hello Philipp,
so I have tried your fix but it seems that the frontend doesn't connect to the backend. I have started both (frontend & backend) on the same machine. Those are the currently running docker images:

So the backend logs this stuff

After fixing the error as you said the frontend has following logs:

In Chrome it does say that it can't connect to 'ws://localhost:15674/ws'.

Do u have any idea why I get these errors? I followed both installations guides.

PhilippSautner97 · 2020-12-14T13:56:15Z

If you follow the guide, your containers should look something like this:

The frontend tries to connect to the ports which don't exist since the incorrect containers have been loaded up.
I have cleaned up some mistakes in the Installationguides, I would suggest you try to follow them again, but make sure to delete/shutdown your docker containers before doing so.

Hey Philipp,

thanks for replying so quickly. I have deleted everything and reinstalled the frontend/backend again.

The frontend shows now this:
