WireGuard Setup not working

Hi,

  1. Please try manually setting a slightly lower MTU, such as 1280, etc.

  2. Can your phone and computer connect to VPN via the WireGuard APP using the VPN profile which is same as Slate7?
    Please take some screenshots to check.

  3. Is your phone or computer connected network source as same as the Slate7?

Please refer this guide to check again:
