App proxy returns 500

Retired Boards Appdev Store Design

I have a proxy hitting my app, it worked perfectly until today.

It stopped working all of a sudden and now spits out 500 (Internal Server Error).

My entry point works fine, that is I can hit it directly and get expected response.

As I can see from the logs the proxy NEVER hits my app but it still says “There was an error in the third-party application.” if I try to do a GET directly in the browser.

I just want to stress that my entry point works fine but proxy never calls it.

I rectreated my app, deleted and recreated proxy, all to no avail.

Any ideas what can be wrong?

500 is gone but it now redirects to “myurl/password” from “myurl/proxy/entrypoint”.

By the way I’m in development environment. Fully logged in to the site.

Any body has a clue what’s going on?

Hi @iandme

Did you find a solution for this issue, as a few of us have had a very similar issue over at https://community.shopify.com/c/Shopify-APIs-SDKs/Application-Proxy-There-was-an-error-in-the-third-party/td-p/529794 from around the same time you posted your issue?

Thanks,

Luke

In my case the issue was incomplete SSL certificate, I was missing fullchain.pem from configuration.

Thanks for getting back so quickly @iandme ,

How did you manage to debug this? Were you using a tool like https://www.sslshopper.com/ssl-checker.html, and if so, did this flag the issue?

Cheers.
