@neelchauhan Unfortunately (I think I alluded to this earlier) the translated files are not edited in this way. The source (English) files need to be changed and then our translation engine (Crowdin) will pick up the changes that our translators will massage and approve. If you want to make this change, modify the English (source) file instead: cloud_server_using_nextcloud.md and delete the other changes the .ko, .it, and .uk files from your PR.

If you don't want to change this PR, close it and just create a new one with the changes to the source file.

I've made the changes, please re-review/approve. Thanks for letting me know.
