403 Error - My Space is inaccessible

I’m getting a 403 error when trying to access my Space:

Space: Astronomy AI - a Hugging Face Space by MZB17

What happened:

• My Space was working fine
• Suddenly started getting 403 error
• Cannot access the App tab

What I’ve tried:

• Restart Space
• Factory Rebuild
• Different browsers
• Clearing cache
• Different networks

My files are all there (app.py, requirements.txt, CSV files)

Can someone please help me resolve this?
