Hi
I’m also having problems with sync from Joplin to Nextcloud!
Im running the last version of Joplin 1.0.201 (Linux Mint 19)
And running last version of NextCLoud 18.0.4
I have downloaded the “Joplin Web API” version 0.0.25 and installed / activated in nextcloud.
I have creted a folder in the root of the files called Joplin

Here is my settings from Joplin!
Any help will be good.
Kind regards
Taxick
HI 
What did this mean: (post withdrawn by author, will be automatically deleted in 24 hours unless flagged)
Looking at the code it seems Joplin expects your WebDAV URL to contain /remote.php/webdav
:
Hi @roman_r_m
Thanks for your answer 
I have changed the URL: https://MY-URL/remote.php/webdav/files/Taxick/Joplin
And now will it not accept my username and password...
but the other check I have problems with before are ok now..
What now? What can i do?
I misread your issue and was giving bad advice that wouldn’t be useful, so redacted it. I jump in too quick at times. Ha
I believe that if you have webdav
in your Nextcloud URL you do not need your username. Try:
https://MY-URL/remote.php/webdav/files/Joplin
I think that we have to fix the Nextcloud web dav URL stuff at one point. A lot of people reported that they actually cannot use the Nextcloud sync target with Nextcloud.
Hi 
Thanks for all your answer 
I have found a solution to my problem. 
Instead of using "Nextcloud" in Joplin sync settings, I used "WebDav"
In the URL: I used this: https://my-site.dk/remote.php/dav/files/MY-NEXTCLOUD- USERNAME/Joplin
And logged in with my username and password from Nextcloud!
Rember to create a folder in nextcloud called Joplin
And now it works.
@Taxick, even though you solved your issue by switching to WebDAV, I propose a possible alternative solution for others that involves filesystem syncing, too.
