Getting warning "The document could not be saved. Please check connection settings"

I am getting the below error while opening a document in OnlyOffice editor :

I checked the logs but there was nothing much other than this line which was repeated several times -

sendServerRequest returned an error: data = "{“error”:0}"

Kindly help me out and let me know how to get rid of this warning which prompts up every time I open the document.

I have read many related questions and none of them have worked for me yet.

hi @Devyansh

If you have valid license, then I’d recommend contacting us via Zendesk to get prompt replies:
