Android App - Malformed Server Configuration on login screen

The Basics

  • Nextcloud Server version (e.g., 29.x.x):
    • Nextcloud Hub 10 (31.0.0)
  • Operating system and version (e.g., Ubuntu 24.04):
    • Docker running on Debian 12 LXC
  • Web server and version (e.g, Apache 2.4.25):
    • Apache bundled with AIO
  • Reverse proxy and version _(e.g. nginx 1.27.2)
    • NGINX Proxy Manager v2.11.2
  • PHP version (e.g, 8.3):
    • PHP bundled with AIO
  • Is this the first time you’ve seen this error? (Yes / No):
    • Yes
  • When did this problem seem to first start?
    • Day 1
  • Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
    • AIO
  • Are you using CloudfIare, mod_security, or similar? (Yes / No)
    • Cloudflare

Summary of the issue you are facing:

Fresh installation of nextcloud-aio. Fresh installation of Nextcloud android app.
When entering the server address in the android app, I get a “Malformed Server Configuration” error and it will not let me continue. No issues logging in through web browser, windows client, or iOS client.

Opened an issue on the Android app’s github and was directed here for support due to having an app installed.

Steps to replicate it (hint: details matter!):

  1. Open android app
  2. Click login
  3. Enter server address (https://nextcloud.mydomainhere.com)
  4. Click on arrow for next screen
  5. Malformed Server Configuration error

Log entries

Nextcloud

Please provide the log entries from your Nextcloud log that are generated during the time of problem (via the Copy raw option from Administration settings->Logging screen or from your nextcloud.log located in your data directory). Feel free to use a pastebin/gist service if necessary.

[PHP] Error: Declaration of Psr\Log\AbstractLogger::emergency($message, array $context = []) must be compatible with Psr\Log\LoggerInterface::emergency(Stringable|string $message, array $context = []): void at /var/www/html/custom_apps/integration_onedrive/vendor/psr/log/Psr/Log/AbstractLogger.php#22
	GET /remote.php/dav/

There are no other logs near the time of login. When disabling the integration_onedrive app, no log appears.

Configuration

Nextcloud

The output of occ config:list system or similar is best, but, if not possible, the contents of your config.php file from /path/to/nextcloud is fine (make sure to remove any identifiable information!):

Try disabling the onedrive integration app, fixed the problem for me.

Got the same issue, only on android devices. macOS an iOS are running whithout any issue.

This solution wored for me.
