I’m not sure what is going on, but cusdis website is down for more than a week, and the domain is expired. Not sure if this was by accident or of the project is now officially dead. In any case, consider to remove the plugin, as having sites loading content from a 3rd party domain who might soon have news owners doesn’t seem a very healthy thing to do, security wise.
According to the project’s GitHub, the last commit was 24 days ago, so I wouldn’t exactly say that it’s dead.
That said, I would definitely recommend self-hosting Cusdis for anyone interested in using it. This is what I’m doing for one of my websites which doesn’t require anything fancy, comment section-wise. The deployment happens on Vercel, and the database is stored on Railway. There’s even a simple “Deploy to Railway” button on the Cusdis GitHub page to self-host both the deployment and database.
Personally, I’m moving towards GraphComment for more complex use cases, but Cusdis still has its uses.
However, Railway implemented their own full deployment, so it’s a loooot easier now. I’d suggest just following Railway’s guide.
Once it’s deployed, go to your Dashboard, click on the app, click on the rounded rectangle, and under “Deployments”, you should find the app’s domain link (it’ll be something like “app-name.railway.app”). You can edit the service domain under “Settings”.
Go to that service domain, login with the credentials you set, and set up Cusdis as you would with the hosted version.
