Errors while connecting

A check order, most common cause first. Follow the order; it saves time.

1. The password

Re-copy it whole. A trailing space or a truncated character is the most common cause, and the least visible.

2. The port

Rotating is 823, SOCKS5 is 824, sticky is 10000–29999. Anything outside those does not answer.

3. Your quota

Check the remaining quota in your console. An account with none left stops serving.

4. Your concurrency

The limit is 5,000. If your tool is set higher, some connections are refused and it looks like random errors.

5. Your targeting

If you are using a fine filter, drop back to country only. A small city sometimes has no IPs available at that moment — and that looks like a failed connection rather than an empty filter.
