Hi,

I activated the SSTP and the OpenVPN, they work properly.

But after a while (<1 hour), the client can not connect to either the SSTP or the OpenVPN.

In the Winbox interface, I simply disable and activate the SSTP and OpenVPN, and it works again right away.

So to overcome this problem I made a script to disable and reactivate the SSTP and OpenVPN every 30 minutes, but it's not very good ...

Do you know why SSTP and OpenVPN servers are unstable on RouterBOARD 750G r3 ?

Best regards.

I've been using SSTP, OVPN and every other vpn/tunnel that MikroTik supports for well over 10 years. I've never had any issues like the one you describe.

First upgrade to the latest version (if not already) and if the problem persists create a supout and send it to support@mikrotik.com

I see the exact same problem with the ovpn and sstp servers on a HEX v3 router (RouterBOARD 750G r3).
This might have something to do with this specific model.

I upgraded the routerboard firmware to 6.42.3 today in the hope of fixing this issue. (routerOS was already on 6.42.3, there do not seem to be any vpn fixes in 6.42.4).

Hello,

I have a same problem that the autor of topic.
If someone has found a solution.

Thanks.

And you provide even less information than the author of the topic. Model, software version...

So if it is also bound to hEX v3 in your case, has any of you three sent an e-mail to support@mikrotik.com with a supout.rif created while the issue exists (the VPN connection is already down and you haven't restarted the ovpn/sstp server yer) as @Cha0s has suggested?

I haven't seen this problem since I updated the routerboard firmware to the same version as the running RouterOS version. It was still on the factory firmware (3.41) before that.
Might be worth a try for TS. Can't reproduce the problem anymore so can't send a supout

Hello everyone,

After doing several searches, it turns out that the problem came from the fact that the certificate (server-certificate) was not trusted, I ticked the box Trusted in System -> Certificate -> server-certificate, and since we have no connection problem.

Thanks for your help.

Best regards.
