How to sync via Nexcloud with free provider?

[MikeMorenoDSP]

Hello,

Operating System and version:  macOS 10.13.6
Browser Name and version: Firefox 105.01

I'm using super productivity on my desktop browser and would like to sync it to my smartphone as well, but I had a persisting issue 504 on my iphone with either Dropbox or Google Drive, so I'm resorting to trying webDAV.

So I'm using a free Nextcloud provider such as the good cloud or tab.digital.
But I fail to see how to do a proper sync.
I exported my data and imported it to Nextcloud and used the following in the super productivity web app, but I still get 504.

Bare URL: https://ann.nl.tab.digital/remote.php/dav/files/[email protected]
Username: [email protected]
Password: ********
Sync File Path: super-productivity.json

Could someone provide me some help on the next steps?
Thank you in advance.

I have almost the same issue!
I'm syncing with my webo.cloud nextcloud account.
1)my linux ubuntu 7.12.0 version works perfectly
2)my smarphone /e/ os, with a 7.12.0 version of superproductivity says:
"Unkonown error during syncronization. Try check the console"

my config is:
Base URL: https://nextcloud05.webo.cloud/remote.php/dav/files/[email protected]/Folder/
Username: [email protected]
pasoword:*****
sync File Path: sp.json

I am not an experienced user. I know this is an already discussed issue but i can't find an easy answer. For example: Can I check the app's console on my smarphone?
Help is very appreciated. Thank you so much
