claude code throwing "Request blocked before it reached Anthropic's API (HTTP 403)" on hotspot connections

[Pixellated Han]

API Error: Request blocked before it reached Anthropic's API (HTTP 403) · the network this request came from isn't allowed

new wording in claude code 2.1.317. hits mobile data and hotspots mostly, or right after switching networks, same region same account. resending the exact prompt often just goes through, relogging does nothing
