Hi,

I'm trying to sync the Joplin Android app with my personal Nextcloud, but when I synchronise (or "Check synchronisation configuration"), the status won't go past "in_progress". After ~3 minutes, the request timeouts with the error "Network request failed" (see log file below).

Here is a screenshot of the log after the timeout :

I don't know if it's a problem with the app or with my phone. My Nextcloud credentials are correct, since I use the same on desktop.

Thank you for your help :)

It might be the same bug as this one: https://github.com/laurent22/joplin/issues/209#issuecomment-364920662 Please download the latest mobile and desktop version for a fix.

Thank you for your answer. I downloaded the latest desktop version (Joplin 1.0.62 (prod, linux)), and I already have the latest on my mobile (android-v1.0.95).

I can confirm the problem is still the same, even after deleting all Joplin data on Nextcloud, re-syncing the Desktop app to Nextcloud, and trying to sync the mobile app with Nextcloud. Nothing is fetched from the mobile app and the log error is "Network request failed".

After you setup the Nextcloud config, if you click on "Check synchronisation configuration" on the config screen, does it work?

[maximelouet]

No, it's the same behaviour.
Here is the result after 3 minutes of loading:

This is strange, it means the app cannot access the internet or the Nextcloud service. Can you access your Nextcloud website from the device's browser? Also do you know if syncing with eg. OneDrive works?

I can access the Nextcloud website from the device's browser. But sync with OneDrive does not work either :

I'm confused by this bug as it seems the app simply does not have access to the network. Is it going through a proxy or VPN?

Seems like this is a bug in Android 7.0 fixed by 7.1.1 being 7.0 only supports ONE elliptic curve: prime256v1

One workaround for Nginx is adding ssl_ecdh_curve prime256v1; to /etc/nginx/snippets.d/ssl_default

Wow... Yeah it was the problem. I changed the setting in nginx and it works now. Thank you for your help :)
