Error to connect the backend

[rubenssoto]

Hey,

Thank you for this amazing software. I'm trying to deploy in my homelab but I think I did something wrong.

My compose:
`services:
searxng:
image: docker.io/searxng/searxng:latest
volumes:
- /data/apps/perplexica:/etc/searxng:rw
ports:
- 4000
networks:
- container-network
restart: unless-stopped

perplexica-backend:
image: itzcrazykns1337/perplexica-backend:main
environment:
- SEARXNG_API_URL=http://searxng:8080
depends_on:
- searxng
ports:
- 3001:3001
volumes:
- /data/apps/perplexica/backend-dbstore:/home/perplexica/data
- /data/apps/perplexica/uploads:/home/perplexica/uploads
- /data/apps/perplexica/config.toml:/home/perplexica/config.toml
extra_hosts:
- 'host.docker.internal:host-gateway'
networks:
- container-network
restart: unless-stopped

perplexica-frontend:
image: itzcrazykns1337/perplexica-frontend:main
depends_on:

environment:
- NEXT_PUBLIC_API_URL=http://127.0.0.1:3001/api
- NEXT_PUBLIC_WS_URL=ws://127.0.0.1:3001
ports:
- 3000
networks:
- container-network
restart: unless-stopped

networks:
container-network:
external: true

volumes:

`

I'm getting this error on the web frontend: Failed to connect to the server. Please try again later.

I only found errors on the searchnx container

Isn’t this because of SSL errors on your Searxng? I have firewall errors on my work laptop so I am testing this on my personal one.

[rubenssoto]

I think the problem is on the frontend...I got some error:

I don't know where this 127.0.0.1 is comming from

[Mkz9s4Vy]

because this project hard-code 127.0.0.1 in its frontend, you should follow this closed issue.
#92

[realies]

#92 does not help if you're using the Docker published images. One way of doing it is: #467 (comment)

There are other ways in the countless issues about it.

[keven1024]

You can use this docker #565, I have solved the problem of variable hardcoding
