I believe UTM doesn't accept Aggressive mode. Change to main mode and I think it will work.

Managing several Sophos UTMs and Sophos XGs both at work and at some home locations, dedicated to continuously improve IT-security and feeling well helping others with their IT-security challenges.

Sometimes I post some useful tips on my blog, see blog.pijnappels.eu/category/sophos/ for Sophos related posts.

Hi, mgunuc, and welcome to the User BB!

That's a great first post. It's the first time that I've seen someone understand enough about IPsec to post the problem in just three log lines. You quickly got the right answer from apijnappels. Cool!

Cheers - Bob
