Sync Function does not update

Maybe try taking the database offline and then back online? Sync Gateway _config REST endpoint not working as expected

Otherwise :

Yes. But I can’t tell if it PUT was selected when the Send was done.

After some research I found out that for some status codes, it may be that the request is changed to a GET operation.

A redirect is HTTP 301, 302 or 307. Are you seeing any of those in the logging?

When I run the request using the curl command that I can copy from Postman, I get this error:

{"error":"Unauthorized","reason":"Login required"}

You’ll need to add the -u username:password option to curl.
