BE550 VPN Not effective
Hello everyone. I purchased 4 BE550 routers. They are all used as VPN Clients, and the servers are deployed in AWS. The VPN functions of 3 of them can be used normally when they first came back. However, three of them upgraded the firmware according to the app prompts, and the VPN failed. The connection was successful. The only one that has not been upgraded can be connected. I downgraded 3 failed routers using the 1.04 firmware from the official website, but they still cannot be restored. I compared the configurations of the effective and disabled routers. They are exactly the same. I don’t understand why. It doesn't work. Does anyone have any ideas?
