[SOLVED] IPsec with 17.1.4 - [IKE] received PAYLOAD_MALFORMED error notify

[Space]

Hello,

I had IPsec running some time ago with 16.7 but I wanted to use OpenVPN since I wanted to add several clients / roadwarriors. I have OpenVPN running but the Android client is not as flexible as I would like. So I wanted to switch back to IPsec. I have setup IPsec according to the cookbook (https://docs.opnsense.org/manual/how-tos/ipsec-road.html but I can't get it to run. I get the following messages in logfile:

Code: [Select]

I have no idea what setting to change or if this is a problem of 17.1.x series ... I know I had it running with 16.7.

Does anyone have an idea?

Thanks and best regards,

Looks like a reboot solved this issue ...
