Gl-usb150 - PPTP - problems after firmware update at 3.01

Hello,
I’ve just update my router to the new firmware version , from 3.00 to 3.01 and after the update the PPtP protocol did not worked (i had to install the protocol, the new firmware did not have the PPtP protocol already installed). The error is "Unknown error (negotiation_failed) the server is accessible and is working if it is accessed by another device.
Also I saw that new protocol it is available PPPoSSH, does anybody configure with success this protocol? Can share with us how to do it correctly?
Thank you!

Maybe you can reconfigure pptp after you install the protocol. This may be caused by upgrading while missing the protocol.

I uninstalled the protocol and reconfigured without success.
I also run the command startvpn with the result:
root@GL-USB150:~# /etc/init.d/startvpn restart
uci: Entry not found
uci: Entry not found
well

this is openvpn script, not pptp.

How did you configure pptp?

I configured the protocol in WEB interface.
There is a command to restart the protocol to see the full log?
Can you also help me with the PPPoSSH configuration?
Thank you!

PPTP is configured in network and you can just restart the network.

/etc/init.d/network restart

I have no experience in PPPoSSH

I try all kind of configurations, unfortunately is not connecting. I even go back to the previous version 3.0 in which is running flawless to check the full system client-server.
Does somebody check this type of connection on version 3.01?
Thank you!

maybe you can just keep using the old firmware.

What is your scenario when using PPTP ? Maybe wireguard is a better option for you.

Thanks for help, I did not managed to make it work. I reverted the firmware to the previous firmware that was working.
Regarding the scenario:

  • VPN server - ROUTER with DD-wrt
    -client usb150 openwrt.
  • the VPN server is used to be accessed by other devices (mobile phone and laptop)
    On version 3.01 I can use the SSH tuel that is working OK - hint for others that encounter also tis problem with the VPN client.
    Regarding the software reverting. Does somebody can help me with a previous firmware 2.6 for example?
    Thank you in advance!
