Status Code: None

Possible cause: Bad proxy or no connection detected.

"Status Code: None" means the marketplace answered nothing at all: the request failed at the connection level, before any HTTP status existed. The two usual causes are a proxy that no longer works and a machine that lost its connection.

Solution:

• Start using proxies
• Switch to working proxies
• Test the connection without proxies once, to tell a dead proxy list apart from a network problem

The proxy groups the app uses live in proxies.bin; see file storage locations for the folder. A proxy that answers but rate-limits you shows Status Code: Too Many Requests instead.
