Why can't snkrs receive the mail?

1, the network is unstable and the network state is not good, which leads to the failure to receive data normally and leads to errors. Suggest changing the network.

2. The same IP in the same area requests too many services at the same time, resulting in being temporarily blocked by the server.

3. Too many times to access the server at the same time, resulting in the slow operation of the server.

This situation can only be solved by waiting for a while or changing ip.
