Custom `HTTP 530` status code by Cloudflare not recognized by Deck Android as offline server

[Goldmaster]

This issue respects the following points:

• [X] I have read the FAQ
• [X] I have searched for existing issues
• [X] The issue affects the Deck Android app, neither the Deck server app nor the Nextcloud Android app.

Describe the bug

When the phone or server is offline, I get a stack trace popup which i then have to close or copy.

Expected behavior

When deck server is offline, either because the nextcloud server is down or phone is offline. I should be able to edit and add cards without issue. Then, when the server is back online, the changes made are reciprocated across to the server, rather than getting some error message.
