Recipe import fails / Server Error 500 #1344

Closed Howy76 closed 2 years ago

Issue

Hi there, I'm new here and trying my hand at the recipe database. Thank you for the great project. The database works for me so far and I can also create new users and recipes myself. However, I cannot import recipes from any external site. In the frontend I get a red popup window and the message: Server Error (500). I have an Apache server running on port 80 with a small homepage. I don't have a domain and I don't want external access to the database.

The container seems to be running fine for me: pi@raspberrypi:/opt/tandoor $ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 64fd832847e5 nginx:mainline-alpine "/docker-entrypoint.…" 2 hours ago Up 9 minutes 0.0.0.0:8090->80/tcp, :::8090->80/tcp tandoor-nginx_recipes-1 0cffee96becb vabene1111/recipes "/opt/recipes/boot.sh" 2 hours ago Up 9 minutes 8080/tcp tandoor-web_recipes-1 eba676f107de postgres:11-alpine "docker-entrypoint.s…" 2 hours ago Up 10 minutes 5432/tcp tandoor-db_recipes-1

Have I perhaps forgotten a small configuration?

do you have your server in a datacenter that might be blocked by chefkoch ? can you try a few different websites to import from ?

generally speaking we have implemented a proper error catch for the future but the issue your log shows indicates that chefkoch is refusing your conneciton

Howy76 commented 2 years ago

Unfortunately, all pages are blocked. My server is a small RaspPi that I have at home. I can also use other browsers like Edge, Chrome or Brave. All the same error message. The recipe pages are displayed normally in the browser.

vabene1111 commented 2 years ago

interesting, i can import from all of those sites. Is there any firewall or network service that could block the requests from your PI ?

Howy76 commented 2 years ago

A firewall (ufw) is not installed. However, I have a network filter running for my home network. It filters the advertising out of the pages for me. PiHole. This filter does not show me any restrictions for the recipe pages. I have already whitelisted them. Brings no improvement. If I disable it, it doesn't work either. Nothing else is installed. I'm a little confused...

The db_recipes container has a console - what happens when you try wget www.lecker.de from that console??

Howy76 commented 2 years ago

Do you mean it like this:

@Howy76 - it doesn't look like your docker container has a functional DNS or can't access the internet - you will need to fix that before url import will function.

Howy76 commented 2 years ago

@smilerz You were right about the faulty DNS. I have in the file

/etc/network/interfaces

added the following entry.

auto eth0 iface eth0 inet dhcp dns-nameservers 8.8.8.8

This gave the container access to the internet and the recipe import functioned.

Thank you very much for your hint.
