Getting an "unexpected error" each time I try to deploy an app

For some reason I get an “unexpected error” each time I try to deploy an app. It happens with both my custom-built files and even templates.

I had a working project in August, but at some point I logged into my Streamlit account and couldn’t see the app. After that I also couldn’t deploy anything.

Tried a lot of things such as relogging, deleting and creating a new reposiotry at GitHub. Nothing seems to work.

Do you know what might be the reason?

To me appears the code 403, is really bothering!

I am in a very similar situation.
In my case, I had recently deployed a clone of the same app because I turned it into a multipage app and wanted to change the name of the main file. Then, I deleted the older version and at first everything was working smoothly. However, after some minutes the app stopped working and disappeared from my app list. Now, whenever I try to deploy it again I get a “Unexpected problem” error (or 403) and cannot proceed. Please help!

P.s. I have noticed in other posts that a potential cause for this problem is trying to deploy more than one private app. However, my GitHub repo is Public and I in any case I have no other apps at the moment.

I’m getting the same. In Dec was able to deploy the app. Came back in Jan and the app was gone. So tried to deploy again but under the URL it says unexpected error.

Read that it might be due to multiple private repos. So i created a new Public repo fresh. Came back and still getting unexpected error on the URL. Doesn’t matter what i type in or keep the auto generated.

Please help i can’t continue

Hi there, I have contacted the streamlit support through the snowflake platform and it turns out my app was accidentally flagged as “malicious usage”. They unlocked my account after checking on my activity. I would recommend doing the same if you end up having a similar problem:
