APP

Why does APP query data fail validation?

The balance query and TX result query of the APP have an anti cheating verification mechanism. If the verification results are incorrect, you may encounter data query verification failure.

When the app starts, it initializes the verification client and extracts the verification nodes from the available gateway nodes. When querying balance and TX status, the query results will be verified with the verification node. If the verification fails, an error will be prompted

What port numbers do servers need to open?

TCP Open Port：80 , 1317 , 8545 , 23478 , 26656 , 28008 , 28043 , 50327 , 50328

UDP Open Port：3478, 50000~55000

Why does the gateway address fail verification? How to solve it?

1.First, explain why gateway address verification failed

Due to the need for gateway addresses to provide external services, it is required that the gateway address must be open to the public.

Therefore, when setting the gateway address, the connectivity of the address will be tested through the internet. When the request fails to be sent or the request result is incorrect, an error will be thrown indicating that the gateway address verification has failed.

2.How to solve the problem of gateway address verification failure

The failure of gateway address verification is essentially due to network access failure, which needs to be addressed from the network layer. Solving requires a certain level of hands-on ability. If there are difficulties, it is recommended to find a partner to help.

  • Firstly, check if the router settings are correct and if the port image is correctly set (refer to the introduction on the current page for a list of port numbers that require an image)
  • If it has not been resolved yet, you can check if the server's firewall is enabled. If it is enabled, please check if the list of ports that need to be opened is already open.
  • If it has not been resolved yet, you can contact the current network supplier and explain the list of ports that need to be opened for their assistance in resolving the issue
