Get 403 forbidden while adding changeset from merkaartor


I am getting “Error transferring - server replied: Forbidden” while posting small changeset via Merkaartor.

I do not understand what is my problem, and I do not know how to properly debug this issue.

I tried to do it from two different internet providers: from mobile internet, and from my work.

Can somebody help me?

merkaartor did not switch to using OAuth 2, which became the only way to log in to the OSM API from July 1


Oh… what a sad story :frowning:
Will try to contact merkaartor developers, may be we will be able to do something with it.

from comments in Deprecation of HTTP Basic Auth and OAuth 1.0a · Issue #286 · openstreetmap/merkaartor · GitHub they seem to be aware already
