I added a Sui wallet in Koinly using a public address. The wallet is created successfully, but when I run a sync, it fails with Remote Error (200) after the sync starts. No transactions are imported at all.

I confirmed the transactions exist on-chain via a Sui explorer (Suiscan), including activity from 2026. I already tried:

Triggering a full resync from the beginning

Deleting and recreating the wallet with the same public address

The wallet still shows 0 transactions and the sync continues to fail with the 200 error.
