Tplink Cloud Router interface prompts "request Failed", how to do?

Introduction to the problem

When creating, logging in, Unregistering tp-link IDs, or when retrieving Tp-link ID passwords, online upgrades, refreshing selected applications, and so on with cloud services, the cloud router or app interface may prompt the sending request to fail, please try again , as shown below.

After this problem occurs, try to resolve the following methods:

Solving method

This problem occurs, typically due to a communication failure between the router and the cloud server, and may be caused as follows:

1 , cloud routers are not networked

A. Cloud routers WAN Port broadband connection, but the WAN port does not dial successfully or network.

B. Cloud router connections are not able to log on to the Tp-link ID when the wireless switch is used (that is, the LAN port is cascaded to the front-end primary router) under other routers.

C. Cloud Router WDS Bridging the front-end wireless signal, setting the cloud router LAN port to manually specify an IP address may result in the inability to log on to the Tp-link ID.

2 , DNS problem

Because a DNS server failure cannot resolve the IP address of the cloud server, it can also result in unsuccessful logon attempts, please try to replace the router WAN port with a DNS address of 114.114.114.114 or 8.8.8.8. The method for modifying DNS is as follows:

Login Router Management interface, click on the routing settings > internet set up, in the Advanced settings to modify the preferred and alternate DNS server, click Save . The following figure:

Note : When the Cloud router WAN port is broadband dial-up, the DNS server for the WAN port cannot be changed.

3 , front-end network issues

Routers cascade to the front-end network through Lan-wan (that is, the router's WAN port is connected to the front-end primary router), but the front-end routers block the cloud server's communication port, causing the router to fail to communicate with the cloud server.

If the router is connected directly to broadband and the WAN port is set up for broadband dial-up access, it is recommended to replace the other broadband line comparison test.

4 , Cloud Server Exception

When a cloud server is busy or maintaining an upgrade, it may cause the router to not use the cloud services properly. It is recommended that you wait for the cloud server to be normal.

If the problem is not resolved after the above operation, please call: 400-8863-400 for technical support.
