Proxy error: Errno::EPROTO 504 in our ZAF app
Hi
Within our app we are doing a ZAFClient request to our server to retrieve some data. This has been worked for a couple of years but a few days ago it stopped working.
We have tested the same request with PostMan and works without any issues
In the devtools our request response looks like:
Req: https://[instance].zendesk.com/proxy/v2/apps/secure/https%3A%2F%2F...
Resp: HTTP 504, Proxy error: Errno::EPROTO
We have recently changed our SSL certs provider from TrustWave to Comodo.
And we have switched domain from .me to .com, but it was a week earlier and after changing URLs in the app everything were working properly.
Any hints how to debug this issue are really appreciated, thanks in advance.

For anyone else that finds this post, you can get more information about SSL requirements for secure settings in our developer documentation:

Hi Michael,
This error is usually caused by the proxy not being able to validate the certificate on the remote server and failing the request to ensure no credentials are leaked.
I'll open a ticket on your behalf over this so we can look into it in detail.
