HOST161: Host rate limited
What this means
The host is rate-limiting this store's tills.
The server keeps answering 429 (too many requests) even though the app is already backing off and honoring the server's Retry-After delays. Several tills on one internet connection share one address, so per-source rate limits treat them as a single very busy client. Syncing continues automatically but will lag until the limit is raised.

Troubleshoot
- Ask the host to raise or exempt the REST API rate limit for the store's own traffic — name the shop's static IP if it has one.
- Security services that count repeated error responses (429s) toward a block (for example Sucuri's IDS) may need the store's API excluded from that counter.
- If several tills share one connection, mention that to the host: one IP here is a whole shop, not one user.
