@slovakia_office, I see four issues here:
- The first issue is the URL. It should simply be
https://kc-eu.kobotoolbox.orgif you are using the EU server formally known as the OCHA server. - The second issue is the use of
KCcapital letters instead of thekc. To correct this, simply use the URL shared above (if you are using the EU server. - The use of the username
tutaponaat the end of the URL is not needed. Please see the URL shared at the top. It should only be the URL. There is no need to keep the username at the end of the URL. - The user is conflicting. Is it
tutaponaorslovakia_office? Use the correct one.
As advised in my previous post, please follow the article properly to configure your app. It should solve your issue.
