Getting 404 after logging in to Penpot

[Algaweb]

Hello,
when on the logging screen of penpot, I can't see login and pass for normal logging in to the app. I can only see OpenID. But when clicking it I get 404 error Not Found nginx.
I have problem logging in to any app with OpenId or Logg in with Cloudron option. Do you know how to set it up or repair it?

Can you run cloudron-support --troubleshoot via SSH on the server to get an overview what might be wrong?

Hello, sure:

I am not that skilled in setting up Cloudron yet but personally I think it might me something with the OpenID login feature. I can't use on any app. It always results in some kind of error.

@Algaweb can you try curl --connect-timeout 10 --max-time 20 https://my.domain.com on your server? Is your server on an internal network?

[Algaweb]

Ok this is what it got me: curl: (28) Failed to connect to my.domain.com port 443 after 10003 ms: Timeout was reached
(domain here replaced with placeholder, but was used with real domain with cloudron dashboard running)
It should not be an internal network as far as I am aware. I can reach it anywhere without restriction or VPN or anything else. But I am not sure how the server is reached within the hosting center if there is some private networking or something.

@Algaweb are you proxying via Cloudflare or is there some application firewall or something like that? I have seen cases where Cloudflare throws a captcha screen which trips apps doing OIDC requests.
