When VPN is turned on in SSH i can't ping anything or do a speedtest

When VPN is turned on, everything in SSH won’t work. Also downloading new plugins is not working.

Any idea how to fix?

Hi. Can you describe it in detail?For example, the product model and firmware version, as well as some information about the vpn.I suggest you try using vpn in the ui first, and then see if the client below has the same problem
