I am prevented from pushing to my repo which I have been using for many months

[Diliup Gabadamudalige]

I have been using bitbucket for some years and suddenly a few days ago i encountered a strange problem.  I am suddenly prevented from pushing to a repo that I have been using regularly for several months. (error 403) says I need an app password which is there and verified. I tried many times and as it was hindering my workflow i gave ownership of that project to a new account and continued with the work. I am a single user and have NO collaborators. 

Then I opened a new project on my computer and set up a project on bb and tried to push that same error. (error 403) says I need an app password which is there and verified.

I created a project on bb and tried to clone it. Then I get an error message saying that I need an app password. This I have and when I check, it says authorized.

My other account works well. So far...

Any ideas from anybody?
