500 Internal Server Error, using Next.js Causing Refresh Infinite Loop

We are encountering a http status 500 issue for all of our sites and we can’t make out why this is happening. Running the site locally using next build and next start works fine. Also in development using next dev. We are clueless how to solve this as we don’t have access to any serverlogs.

Branch deploy URL:
https://development--midas-capital-dapp.netlify.app/

Preview URL:

https://testnet.midascapital.xyz/ (not loading anything, should actually also work)
https://testnet.midascapital.xyz/en (if no wallet connected works, if wallet connected infinite refresh loop with status code 500)
https://testnet.midascapital.xyz/en/56?sortBy=supply (deeper route, same issue, 500 Loop)
site-name: midas-capital-dapp
site-id: 4e389938-790e-4adb-bfc9-0e3d47dafd64

Moving static page files to serve from CDN...
Moved 0 files
Skipped moving 8 files because they match middleware, so cannot be deployed to the CDN and will be served from the origin instead.
This is fine, but we're letting you know because it may not be what you expect.
The following middleware matched statically-rendered pages:

- /true/_middleware

────────────────────────────────────────────────────────────────

The following files matched middleware and were not moved to the CDN:

- default.html
- default.json
- en.html
- en.json
- default/status.html
- default/status.json
- en/status.html
- en/status.json

────────────────────────────────────────────────────────────────

There are 4 statically-generated or ISR routes that match a middleware function. Matched routes will always be served from the SSR function and will not use ISR or be served from the CDN.
If this was not intended, ensure that your middleware only matches routes that you intend to use SSR.

Side note: if you’re using Netlify DNS as per your screenshot, you shouldn’t have to configure the DNS like you’re doing.

Was able to fix a few issue we had.

We don’t want to use the apex domain for our netlify deployment. If we use a subdomain app, we get branchname.app.midascapital.xyz. Which is fine but we would rather use testnet.midascapital.xyz so I guess this DNS entry is necessary?

Furthmore a weird behaviour is that the index page of our nextjs app is not openend. So on local and on vercel it worked just fine. Here on netlify we have to go to /97 for example. Any idea why this could be?

https://development--midas-capital-dapp.netlify.app/97

On the / page it’s just not loading anything from our app. So weird and getting these errors on the console.

As I said, if you’re using Netlify DNS, adding no record is required. It’s done automatically.

About the other issue, it seems you’ve resolved it as I can now load your page.
