Error: Http failure response for http://hydrusclient:45869/verify_access_key: 0 Unknown Error

Issue

Trying to setup hydrus-web in docker.

After enabling the client_api, configuring, and adding the access key. I go to configure hydrus-web and get
Error: Http failure response for ... :45869/verify_access_key: 0 Unknown Error

I've tried using http instead of https and get the same error. I can confirm the service is listening on the network and that I can reach it from the hydrus-web container.

I do not see anything useful in the logs from docker-compose.

Firstly, the Hydrus Web container does not talk to your Hydrus client. It is just a basic web server hosting the same static files as https://hydrus.app/. When you use Hydrus Web your browser directly connects to your Hydrus client API and thus the Hydrus API needs to be exposed to whichever device you're using Hydrus Web on. Additionally, Hydrus Web works best when it is hosted with valid HTTPS and when Hydrus Web is using HTTPS your Hydrus API needs to be too. Thus the Hydrus Web docker container was designed with the assumption that you would have a reverse proxy for both Hydrus Web and the Hydrus client API. I would recommend something like Caddy or Traefik for this purpose. Both can provide automatic HTTPS using Let's Encrypt.

If you are hosting this on a machine internal to your network, I had to use my-host-machine-ip for the hydrus client's URL, rather than hydrusclient. something like http://192.168.0.10:45869.

when accessing my client api through browser like http://192.168.0.10:45869 as you mentioned above, it works and able to see that welcome page. But when i use the same in hydrus web i get the above error, Am i missing something?

For Anyone who may face this issue like me, Here's how you I fixed this:

1. Ran both hydrus-client and hydrus-web behind traefik (reverse proxy)
2. Enable the client-api service inside hydrus-client with these options: allow non local connections, support CORS headers
3. Im using a self signed certificate for ssl. so did not enable https in above. Also had to hit the hydrus-web domain beforehand in my browser and accept the connection (it will say cert is untrusted and whether to proceed)
4. Finally enter the domain of hydrus-client (which is pointed to the API port of hydrus-client) and Key in the API configuration page of hydrus-web
5. If you see a small window popup at bottom saying all permissions have been given, it means it started working
