Nextcloud: Access Forbidden: Invalid App Password Issue

ℹ️ Support
1

Hi,
When attempting to access my NextCloud server via the link “https://nextcloud.prodesigners-omvcloud.duckdns.org”, I receive the message “Nextcloud - a safe home for all your data,” prompting me to install the NextCloud app. Upon installation and subsequent attempt to access the server using the application-generated link, I am prompted to enter my username and password. However, upon entering the credentials and clicking on “Grant Access,” I am met with the following error message:

“Access Forbidden Invalid app password Nextcloud – a safe home for all your data”

This issue persists despite multiple attempts, and I am unable to access my NextCloud server through the application.
Thank you in advance for your time and assistance.

Hi @abdellah_gasmi, your nextcloud server seems misconfigured or something went wrong in your apache2/nginx config because a login page should be displayed.

Can you provide more information like nextcloud version, type of installation ( VM , docker, manual, snap)
web server software : (nginx, apache2,…)
errors related to your issue

@abdellah_gasmi are you using a reverse proxy behind your nextcloud?

10

@Mageunic No, I’m not using a hardware reverse proxy. Instead, I’ve configured a software-based reverse proxy to handle requests to my Nextcloud instance.

11

@abdellah_gasmi maybe your reverse proxy isn’t correctly set up. can you provide your configuration file for nextcloud reverse proxy (hide your private data)
